In 2003, the legendary UAZ-469 (3151) was replaced by the UAZ Hunter. The new model retained the utilitarian look of its predecessor, but had a fundamentally new platform, the main feature of which was the more durable and reliable Spicer axles. Let's figure out how the front axle of this type of UAZ is designed and how it differs from previous designs.
Diagram of the Spicer front axle on a UAZ.
Construction and maintenance of UAZ-Hunter drive axles
Single-stage drive axles are installed on UAZ-Hunter and UAZ-31519 vehicles.
The main gears and differentials of the front and rear axles are similar in design. The front axle is a rigid hollow beam, inside of which the main (hypoid) gear and differential are located.
From the main gear of the UAZ-Hunter, UAZ-31519 axle gearbox (Fig. 1), torque is transmitted to the front hubs through axle shafts connected by wheel release clutches.
The axle shafts are single parts with constant velocity joints.
Fig. 1 - Main gear (drive axle gearbox) UAZ-Hunter, UAZ-31519
1, 26, 34, 36, 37 – bolts; 2, 33 – spring washers; 3 – driven gear; 4, 24 – axle shafts; 5 – adjusting ring for differential axial displacement; 6, 22 – bearings; 7 – spacer sleeve; 8 – outer race of the outer roller bearing; 9 – roller bearing; 10 – thrust ring; 11 – oil seal; 12 – reflector; 13 – flange; 14 – washer; 15 – nut; 16 – drive axle housing; 17 – adjusting ring of the drive gear; 18 – outer race of the internal roller bearing; 19 – internal roller bearing; 20 – oil scraper ring; 21 – shaft assembly with drive gear; 23 – adjusting nut of differential bearings; 25, 39 – differential box cups; 27, 40 – support washers for the axle gears; 28, 43 – axle gears; 29, 45 – differential satellite axes; 30, 41, 44, 46 – differential satellites; 31, 38 – differential bearing covers; 32 – retainer for the differential bearing adjusting nut; 35 – main gear housing cover; 42 – final drive housing cover gasket
Drain the oil through hole 2 (Fig. 3 and 4), located in the lower part of the crankcase, while also unscrewing plug 1 of the inspection hole.
The axial clearance in the bearings of the drive gear of the UAZ-Hunter, UAZ-31519 axle reducer of more than 0.05 mm is not allowed, since if it is present, rapid wear of the gear teeth occurs and the bridge may jam.
Check the presence of axial play in the bearings by rocking the drive gear by the driveshaft mounting flange.
Axial play in the final drive differential bearings is also not allowed. Check it by rocking the driven gear with the crankcase cover removed or through the oil filler holes.
If gaps are detected, the axle of the UAZ-Hunter, UAZ-315195 vehicle must be adjusted. The front wheels of the car are always on.
The front axle and downshift are switched on and off using the transfer case lever.
Rice. 2. Adjusting the angle of rotation of the wheels of the front drive axle UAZ-Hunter, UAZ-315195
1 - rotation limitation bolt; 2 - lock nut; 3 - stop-turn limiter
When inspecting the steering knuckles of the drive axle UAZ-Hunter, UAZ-31519, pay attention to the serviceability of the adjusting bolts 1 (Fig. 2) and the stops of the wheel rotation limiters 3.
The angle B of the right wheel turning to the right and the left wheel turning to the left should be within 26-27°.
An increased angle of rotation of the wheels leads to contact of the wheel with the suspension parts.
Fig.3. Front axle UAZ-Hunter, UAZ-31519 with one-piece crankcase
1 - filler plug; 2 - drain plug; 3 - safety valve; 4 - lower nut, king pin, oiler
During operation, adding lubricant to the spherical pins and ball joints is not required (bridges shown in Fig. 3). During repairs, the lubricant in the units is replaced.
Adjustment of the tightening of the pivot pins of the steering knuckle of the driving front axle of the UAZ-Hunter, UAZ-31519 is carried out with a preload along the common axis of the pins.
When operating the vehicle, pay special attention to the tightness of the steering knuckle pins.
When the rubbing spherical surfaces of the liners or pins wear out, the preload disappears and a gap forms along the common axis of the pins. Eliminate this gap by tightening the clamping sleeve.
Operation of the front drive axle with gaps in the kingpin assemblies leads to premature failure of the upper kingpin liner.
Under operating conditions, it is most convenient to tighten the clamping bushing of the lower kingpin of the UAZ-Hunter and UAZ-315195 axles:
— remove the cover with the gasket;
— use a special wrench to tighten the clamping sleeve until the gap is eliminated (after hitting the threaded end of the king pin with a copper hammer);
— by turning the key 10-20°, tighten this bushing to create a preload along the common axis of the pins;
— install the cover with gasket;
— tighten the kingpin nut with a torque of 80-100 Nm (8-10 kg/cm) (see Appendix 2).
Exceeding the tightening torque will lead to a decrease in preload and failure of the pivot assembly.
The turning torque of the ball joint (or the steering knuckle housing, if the ball joints were not disconnected from the axle housing) with the O-rings and the steering knuckle hinge of the drive axle UAZ-Hunter, UAZ-31519 removed in any direction relative to the common axis of the pins should be within 10- 25 Nm (1.0-2.5 kg/cm).
If the control parameter is not achieved, then re-tighten the clamping sleeve by turning the wrench another 10-20° and tighten the nut to the specified torque.
If it is impossible to eliminate the gaps by tightening the threaded bushing, it is necessary to replace the liners of the front axle pivot units.
Rice. 4. Front axle UAZ-Hunter, UAZ-315195 with a vertical crankcase connector

Some models of UAZ-Hunter and UAZ-31519 vehicles can be equipped with the axles shown in Fig. 4, with pins, to which it is necessary to add lubricant during operation.
To lubricate the kingpins, grease nipples 4 are installed on the steering knuckle lever (right) and on the upper lining of the kingpin (left).
Eliminate the gap between the ends of the pins and the support washers of the ball joint, which is formed when the rubbing surfaces wear, by removing the same number of adjusting shims from above and below.
The difference between the total thicknesses of the upper and lower gaskets should not exceed 0.1 mm.
Dismantling the differential of the front axle UAZ-Hunter, UAZ-31519
— Remove the differential assembly with the driven gear.
— Press the bearings off the differential box axle.
— Remove the ten bolts securing the driven gear to the differential and remove the driven gear.
— Remove the eight bolts of the differential box cups and separate the cups.
— Remove the differential gears and satellites with axles.
— Reassemble the differential in the reverse order of removal.
Removing the main gear of the front axle gearbox UAZ-Hunter, UAZ-31519
The main gear is removed for repair or replacement.
— Remove the plug and drain the oil from the rear axle.
— Remove both axle shafts
— Disconnect the left tie rod end from the steering gear bipod and move the tie rod to the side.
— While holding the bolts from turning, unscrew the four nuts securing the propeller shaft to the gearbox flange of the front axle UAZ-Hunter, UAZ-315195 and move it to the side.
— Remove the ten bolts securing the main gear housing cover and remove the cover.
— Clean the mating surface from the old gasket.
— Unscrew the nut securing the front axle drive shaft flange.
— Remove the flange with the reflector.
— Remove the four bolts securing the differential bearing caps, remove the caps and remove the differential assembly with the driven gear, and then the shaft with the drive gear assembled with the rear bearing.
— Remove the flange seal.
— Remove the front pinion shaft bearing from the front axle housing.
— Press out the outer races of the front and rear drive gear shaft bearings from the crankcase.

False signs of breakdowns
Front axle on a car
UAZ is one of the few cars that is almost 90% made of metal. Due to poor sound insulation and a large number of parts with gaps, it is very difficult to establish the true cause of the breakdown by ear. The sound “walks” along the frame of the car in any way. Quite often, people climb into the front axle when their transfer case or some other transmission element makes noise. Therefore, it is best to detect a breakdown based on sound not from inside the car, but from outside the car, with an assistant behind the wheel.
Another common false sign, which many people confuse with a broken grenade, is a knocking sound due to a poorly screwed wheel. Therefore, before leaving, it is necessary to check the fastening nuts as carefully as possible. Noise can occur due to a broken or loose suspension, or gaps in the rods. Oil stains on the asphalt in the area where the rear axle is located may be due to leaks in the upper components of the transmission flowing down the driveshaft to the differential.
In a word, there are a lot of nuances, so before disassembling the car and starting the long and labor-intensive procedure of dismantling the bridge, you need to make sure that the breakdown lies specifically in it, and not in some other component or assembly. Sometimes it’s better to go to a service than to try to make a diagnosis yourself.
UAZ hunter front axle device diagram
The UAZ Hunter has long been extremely popular not only among military and civil services, but also among ordinary citizens. This easy-to-maintain and inexpensive SUV gives an indescribable feeling of freedom: you can go on any journey, even the most extreme and difficult one. However, operating this vehicle requires certain technical knowledge and skills. For example, bridges require close attention. When they break down, the car almost always loses the ability to move further. Despite the relatively simple design and good protection from stones, tree stumps and other obstacles encountered off-road, these transmission elements are quite difficult to repair. Diagnosing their malfunctions is also a very complex procedure.
Regarding non-asphalt operation

Off-road, the vehicle's lifespan is slightly less than entirely dependent on the spacer between the steering wheel and pedals. In order to drive a UAZ off-road, you don’t need to break your mind.
The UAZ is a specific car that not everyone needs, and yet Sollers successfully sells them. And the fact that someone doesn’t have enough money to buy a UAZ is not Sollers’ problem.
Why does the plant need a margin of safety, just increase the price in vain? Those who buy cars from a showroom don’t need this. “Athletes like” will buy themselves an old Toyota and everything will be fine with them.

Rear axle structure of UAZ 469
The rear axle of the car is structurally different from the front axle. It does not have a wheel turning mechanism. The rear axle is driven by a cardan shaft from the transfer case. The rear axle consists of the following elements:
Carter
The crankcase consists of two halves. They are connected to each other using bolts. At the bottom of the crankcase there is a hole for draining lubricant. From the side of the wheel mechanisms, axle housings are pressed into the crankcase. In the front part there is a hole for installing the drive shaft.
REFERENCE: The UAZ-469 model is equipped with two types of bridges - military and collective farm. Depending on the type of bridge, the crankcase design differs.
Gearbox
The rear axle of the UAZ 469 has a gearbox consisting of a main gear and a cross-axle differential. The main drive gear is small in size. It transmits torque to the driven gear. The gear teeth are angled. This design allows to reduce the noise level during operation of the unit.
On one side, a drive gear is installed on the drive shaft. On the other side there is a flange necessary for attaching the propeller shaft. To prevent slippage of the drive shaft, splines are provided in the flange. The flange is secured with a nut.
The drive shaft is mounted on bearings. The bearings and moving parts of the gearbox are lubricated with gear oil. To prevent lubricant leakage, oil seals and gaskets are installed.
Inside the driven gear there is a cross-axle differential mechanism. It is made in the form of 4 bevel gears mounted on axles. The cross-axle differential allows the wheels of the axle to rotate independently of each other.
Half shafts
The design of the rear axle of the UAZ-469 provides for the presence of axle shafts. They are necessary to transmit torque to wheel mechanisms. The splined part of the axle shaft is included in the cross-axle differential mechanism. On the other side, the axle shaft is connected with bolts to the hub.

Regarding collective farm bridges. The main difficulty in repairing them is to roll out the bridge from under the UAZ and roll it back, to find adjusting washers of the required thickness on sale, to find on sale not Chinese, but lower-quality domestic bearings.
This bridge with hubs was initially designed for standard Ya-245-I tires weighing 26.5 kg, which on metal stamping weighs about 10 kg. If you stay with the wheels and tires within the standard parameters, then the collective farm bridge will be practically indestructible. And on 35 sneakers with heavy wheels with a negative offset, all UAZ axles will be consumables. That's the whole fairy tale. Hence all these touching stories about torn axle shafts, crumbled gears and other scales.
Take the floor | What are these people saying?
Design Features
The axle housing consists of a one-piece cast main gear housing, axle shaft housings (stockings) pressed into it, and a stamped housing cover.
The absence of a connector in the transverse plane of the bridge gives the structure high rigidity, the unloaded connection between the cover and the crankcase reduces the likelihood of leakage at the joint, and the placement of the main gear and differential in a single crankcase ensures high precision of engagement and more favorable conditions for the operation of bearings.
Thanks to all these design features, the actual service life of bridges has increased significantly. In addition, now to access the main gear and differential there is no need to remove it and “halve it” - you just need to remove the cover.
To reduce warping of the driven gear during its heat treatment and, as a result, reduce noise, increase the reliability and durability of the main gear, the thickness of the “substrate” of the driven gear was increased by 8 mm. However, this measure led to a change in the left differential cup. But, the new differential can be used on previous single-stage axles with a split crankcase, provided that a compensator ring is installed on the cup stud.
Spicer bridges are unified with single-stage bridges of the old design in a number of other details. These are differential bearings, rear axle axle shafts and almost all parts of hub units. The front bearing with a double seal (469-2307086-03) and the new double-edge seal of the drive gear flange are unified with similar parts of U-shaped (“military”) axles produced by UAZ OJSC.
As for the front drive and steering axles, here, in addition to the above points, it should be noted the new constant velocity joints ( CV joints ) of the " Birfield " type, which are much more durable than the hinges of the old design (" Weis "). Currently, all bridges of the Spicer and Timken types are equipped with such hinges. It would be worth recalling that to lubricate the Birfield hinges, a special CV joint grease is used, which must be placed not into the entire internal cavity of the steering knuckle, as before, but only into the hinge itself. The use of other types of lubricants, including the traditional Litol-24, is unacceptable. During operation, adding lubricant to the joint is not required. The internal cavity of the steering knuckle is still filled with Litol-24 lubricant.
Main gear: 1 – bolt; 2, 33 – spring washers; 3 – driven gear; 4, 24 – axle shafts; 5 – adjusting ring; 6, 22 – bearings; 7 – spacer sleeve; 8 – outer race of the outer roller bearing; 9 – roller bearing; 10 – thrust ring; 11 – oil seal; 12 – reflector; 13- flange; 14 – washer; 15 – nut; 16 – axle housing; 17 – adjusting ring of the drive gear; 18 – outer race of the internal roller bearing; 19 – internal roller bearing; 20 – oil deflector ring; 21 – shaft with drive gear; 23 – adjusting nut of differential bearings; 25, 39 – right and left parts of the differential housing; 26 – bolt; 27, 40 - support washers for axle gears; 28, 43 – axle gears; 29, 45 – differential satellite axes; 30, 41, 44, 46 – differential satellites; 31, 38 – differential bearing covers; 32 – retainer for the differential bearing adjusting nut; 34, 36, 37 – bolts; 35 – main gear housing cover; 42 – final drive housing cover gasket
The ones produced have a gear ratio of 4.111 (37:9) or 4.625 (37:8). Axles with a gear ratio of 4.111 are installed mainly on cars with gasoline engines, and with a gear ratio of 4.625 - on cars with diesel engines.

I do not agree with this assessment of the UAZ bridges. IMHO - military bridges are a thing in themselves, and spicers and collective farms - both are never marzipans.
If the car is used correctly (if not for sport), you may not live to see the front axle repaired; the rear axle has a mileage of 100-150 thousand. I did it once and forgot for many years. Not critical at all. Usually, during repairs, the main pair is replaced. So the main pair for my collective farm costs about 2.5 thousand, and for a spicer about 5 thousand. And for 2.5 thousand I can pump out my bridge without any problems and pump it back in.

Front axle UAZ 469
The design of the front axle is different from that of the rear axle. The crankcase is shifted to the right edge in the direction of travel of the car. This is due to the location of the transfer case. The front axle is driven by a driveshaft from the drive shaft. The axle is equipped with rotating mechanisms and steering rods that are used to control the vehicle.
The driver can turn on the front axle on the UAZ 469 without leaving the cabin. To do this, transfer case control levers are installed between the driver and passenger seats. One lever is responsible for turning the front axle on and off. The second is necessary to reduce torque transmission.
Half shafts
The axle shafts have different lengths. This is due to the location of the gearbox. To transmit torque to the wheel mechanisms, regardless of the angle of rotation, CV joints are provided.
IMPORTANT: The design of the front axle of the UAZ 469 provides for disconnecting the axle shafts from the wheel hubs. The connection is made with a specialized screw. This design allows you to increase the service life of the gearbox when driving on good quality surfaces and saves fuel.
Carter
The front axle housing is made of two parts connected by bolts. To avoid pressure build-up when the lubricant heats up, the crankcase is equipped with a breather valve. It allows the air mass to freely escape into the atmosphere. The breathing valve is protected from dust and contamination by a cap.
Steering
The wheel mechanisms are connected to each other by a transverse rod. The rod connection is hinged. To adjust the wheel toe angle, the rod is equipped with ends with threaded connections.
The forces from the steering column are transmitted to the bipod of one of the steering knuckles. The steering knuckles are equipped with king pins.
Re: I disagree again
from: whiteobserver date: Mar. 17th, 2022 07:52 am (UTC) Link
Any angle of a balanced cardan, if it does not bite the hinge, does not transmit any radial load. The forces on the shank are because the bearings are placed so close there that even additional support is needed. The Spicer took this into account. And the warrior is therefore more alive.
Cardan shafts on UAZ die from bad metal. And the front cardan (if the front is connected on asphalt) dies even faster due to the difference in speed of the cardan flanges with non-parallel flanges. And in front the flanges cannot be parallel. The torquey rear driveshaft lasts for decades without any play in the splines. UAZ - well, it’s funny even to remember.
Node maintenance
The axles of the UAZ 469 are distinguished by their reliability and durability. For normal operation of units, they must be regularly maintained. To do this you need:
- Inspect the crankcase and wheel mechanisms for lubricant leaks;
- Check the degree of tightening of the fastening bolts;
- Replaces lubricant;
- Clean the breathing valve from dirt and check its functionality;
- Check the integrity of gaskets and seals;
- Check the play of the front axle turning mechanism.
Possible malfunctions and ways to eliminate them
You can repair the front or rear axle of a UAZ 469 yourself. This will require a standard set of tools and minimal technical knowledge. Possible malfunctions:
Presence of oil smudges
The appearance of oil streaks on the crankcase body or at the hub mounting points indicates a violation of the sealing of the unit. The cause of the violation may be failure of the breathing valve. When heated, the lubricant expands and pressure is created in the axle cavity. Under the influence of pressure, the integrity of gaskets and seals is compromised.
To eliminate the malfunction, it is necessary to restore the functionality of the breathing valve and replace the failed seals.
IMPORTANT: When installing gaskets, it is necessary to treat their surfaces with sealant. Lubricant should be added after the sealant has completely dried.
Increased noise
An increased noise level during operation indicates severe wear of the rotating parts or water entering the unit. When driving off-road or fording, water enters the axle cavity through the breathing valve. This leads to poor lubrication of rotating parts.

Design of the Spicer front axle of UAZ-Patriot, UAZ-Hunter cars
The main gear and differential of the front and rear Spicer axles of the UAZ-Patriot and UAZ-Hunter vehicles are similar in design. All instructions for maintenance and repair of the rear axle also apply to the front axle.
The front drive axle of Spicer UAZ vehicles is steerable.
To make driving easier, the front steered wheels have camber (not adjustable) in the vertical plane and toe in the horizontal plane.
To return the wheels to the middle position, the steering knuckle pins are tilted in the longitudinal and transverse planes. Positive camber is the deviation of the upper part of the wheel from the vertical plane outward.
The camber angle at the Spicer drive axles of UAZ-Patriot and UAZ-Hunter vehicles is α=1° – 30´. Wheel camber affects tire wear. With a camber of up to 2°, wear will not be very large.
During vehicle operation, due to wear of the pins, bearings and fatigue wear of the bridge beam, positive camber gradually decreases to zero, and then the deflection of the wheels moves towards negative camber, which worsens the steering of the wheels.
Fig.1. Spicer front axle of UAZ-Hunter, UAZ-Patriot cars
As a result of the tilt of the wheels during camber, forces arise that tend to return them in different directions when moving.
Lateral wheel slippage occurs, which contributes to tire wear and makes driving difficult. To eliminate the harmful effects of camber, wheels are installed with toe-in.
At the same time, the distance between the wheel rims at the level of the front axle in the front is several millimeters less than in the rear.
The longitudinal inclination of the kingpin of the front drive axle Spicer of UAZ vehicles is designed to stabilize the steered wheels in the middle position, but its effect is noticeable only at high speeds with significant centrifugal forces.
Measurements of wheel stabilization when the car exits a turn are the stabilizing moment and the angular speed of rotation of the wheel when returning to the neutral position.

Adjusting the pivot pins of the front axle Spicer of UAZ cars
When servicing the front drive axle Spicer, check and, if necessary, eliminate the play in the kingpin bearings, wheel toe-in and maximum wheel rotation angles, check and tighten the steering knuckle arm fastening.
When inspecting the steering knuckles, pay attention to the serviceability of the wheel rotation limiters, bolts and the reliability of their locking.
Adding lubricant to spherical pins and ball joints with Bierfield type joints (see Fig. 2) during operation is not required.
During repairs, the lubricant is replaced. Use only recommended lubricants. (To lubricate Birfield-type constant velocity joints, use CV joints-4, CV joints-4M or imported analogues).
Adjustment of the tightening of the ball pins of the Spicer bridge (see Fig. 2) of the steering knuckle at the factory is carried out with a preload along the common axis of the pins.
Maintenance
Maintenance of the UAZ bridge is simple and comes down to monitoring the level of lubricant and topping it up and replacing it. The second point is to check the seals for leaks. It is regularly necessary to check the reliability of the fastenings, especially if the machine is used in difficult road conditions. Eliminate axial play in the differential bearings in a timely manner.
Assembly and connection diagram
When assembling the structure, do not remember several features:
- Press the bushing into the trunnion flush with the end of the washer socket. After completing the procedure, the sleeve must be deployed;
- Place one thrust washer inside the trunnion, the second - in the support. The oil lines in the thrust washers should face the joint. The washer is secured by punching in 3-4 places;
- When installing the hinge, add lubricant to the ball joint;
- Treat the pins and bushings with liquid lubricant.
To obtain the required axial tension, you need to select a certain number of spacers (but not less than five). They are installed on the ends of the knuckle body at the top and bottom. Their number should be the same. Soak the felt ring of the ball joint oil seal with engine oil. If possible, check the bridge on a bench after assembly. If the assembly is done correctly, the axle shafts should not heat up or make excessive noise when braking. Leaks through seals, cuffs, and bolted connections are not allowed.

That's what I'm talking about. Sollers has no need. Serious jeepers will buy a foreign car. Those forced to buy a UAZ will not go anywhere.
But this does not negate the fact that collective farms are crap, outdated already in the middle of the last century, they are amateur warriors, and the Spicer is the pinnacle of what UAZ engineers dared to tear apart.
Although, now barriers for garage Morlocks are in fashion. Some modern cars already require body removal to replace the mounted internal combustion engine. On this wave, removing the bridge to tune it is an exotic vintage, like lifting weights in the gym or buying expensive torn clothes.
But I don’t follow fashion, I need something that is easy to repair if it often breaks.
