Algorithm for replacing the front axle axle seal of the UAZ “Patriot”

The UAZ Patriot and Hunter SUVs are equipped from the factory with two drive axles: front and rear. Thanks to the presence of two axles on the UAZ Patriot SUV, its cross-country ability is unparalleled. The front axle, unlike the rear, is steerable. This indicates that the front axle is engaged only when necessary. The bridge that is installed on the UAZ is called Spicer. It was developed back in the 90s, and every year it was improved and supplemented. Today there is such news that Spicer will soon displace the old designs of units that are installed on “loaves” and “goats”.

Today we will pay attention to the Spicer front axle of the UAZ Patriot SUV. What it is, features, advantages and method of adjusting the product.

Front axle oil seal size UAZ Spicer

Yesterday I changed the seal on the right axle shaft of the front axle, the old one died and oil was pouring through the fist.
I prepared in advance, the size of the original oil seal is 32x50x10, I bought an oil seal of this size, but without an iron cage. I pulled out the old one with difficulty, put in the new one - and it sits down without effort, I turned the axle shaft by hand - the oil seal rotates together with it. I measured it with a caliper: the old one is 50mm in diameter, the mounting hole is 50mm, the new one is 50mm - how can that be??

Has anyone installed modern oil seals, or do you need to look for the original ones in an iron cage?

30x50x10 in a metal frame (left) and 32x50x10 (right). Axle shaft with a diameter of 32mm. Same problem as you.

The one on the right sat on the sealant, letting it harden for a day.

In the photo, the one in the clip is even visually smaller. if size 51 existed, but size 52 obviously wouldn’t fit. Although I might buy it and try it purely for fun.

I couldn’t leave it to dry, my garage is narrow, I had to go out and disassemble it there, and then reassemble it accordingly. I hope it works.

At least now I know that I’m not the only one with this problem, thanks for the answer.

Front axle features

The Spicer axle housing consists of a cast material into which the axle shafts are pressed. The axle housing is closed using a crankcase cover. The transverse plane of the device does not have a connector, which increases reliability and adds rigidity to the structure. Also, the differential and main gear of the Spicer bridge are located in one housing, which determines the high precision of engagement and operation of the device. All these features lead to an increase in the performance of products. Now, in order to service the device, it is enough to remove the crankcase cover and carry out the necessary repairs or replacement of products. Periodic monitoring of the oil level in the system, timely replacement of seals and bearings, as well as elimination of play in gears and differentials - all this is the main criterion for servicing the unit. The Spicer bridge is equipped with new types of joints (CV joints), the feature of which is durability. These hinges require periodic lubrication of the structure, for which CV joint-4 material is used. It is unacceptable to use Litol-24 to lubricate joints. An equally important point is the gear ratio of the Spicer bridge. Devices are available with two front axle ratios for the UAZ Patriot: 4.11 and 4.62. Axles with a value of 4.11 are installed on a UAZ Patriot SUV with a ZMZ 409 gasoline engine, and 4.62 on ZMZ 514 diesel units.

Estimaho & Praddi has significant experience in the development and manufacture of lip seals, producing all the current standard lip seal designs according to DIN 3760 / 3761 and ISO 6194 standards for static and moving vehicle components. The base material for enEspra cuffs is rubber compounds based on Viton fluorinated rubbers, Perbunan nitrile rubbers and MVQ silicone rubbers, which have best-in-class thermal and chemical resistance, aging resistance and stability of mechanical properties and volume. The angle of attack of the working edges of the cuffs is designed using a dynamic modeling system that takes into account the influence of such factors as: pressure of the sealed medium, peripheral speed, runout and shaft misalignment. The edges themselves, of which there can be from one to four, are manufactured with precision precision and ensure absolute sealing of the assembly (or instant pumping of oil from the air zone, in the case of a dynamic fit on the shaft). The design of the cuffs may, in addition, imply the presence of an additional dust-proof edge on the outer radius.

Advantages of the Spicer Bridge

The UAZ Patriot SUV is equipped with a wide type front device.
The advantages of this design are the following: • Increasing the track, which has a positive effect on the stability of the vehicle both on and off-road. The track was increased to 160 cm. • This also had a positive effect on the possibility of increasing the steering angle of the front wheels to 32 degrees. In this case, the SUV received better maneuverability on the road and abroad. • The strength class of the steering knuckles has been increased, thereby reducing the frequency of lubrication and repair work. • Thanks to the presence of a new suspension, the UAZ Patriot received better handling and stability.

Thus, these advantages indicate that the SUV has high off-road stability, as well as cross-country ability, which is important for such a unit.

Replacing the drive gear shaft seal of the front axle reducer

Replace the oil seal if oil leaks are detected from under the gearbox flange.
An oil leak can also be caused by excess oil in the crankcase or a clogged breather.
You will need
: a 27 socket socket, a wrench, a flat-blade screwdriver, a torque wrench.
1
.
Brake the car with the parking brake and place chocks under the rear wheels of the car. Raise and place the front of the car on supports. 2
.
While holding the bolts from turning, unscrew the four nuts securing the propeller shaft to the front axle gearbox flange, remove the bolts and move the shaft to the side. 3
.
Unscrew the nut securing the front axle drive shaft flange and remove the flange with the reflector. 4
.
Using a screwdriver, remove the oil seal from the axle housing. 5
. Using a suitable size mandrel, press the new oil seal into place.

You can use an old oil seal as a mandrel.
6
.
Install the parts in the reverse order of removal. 7
. Tighten the front axle drive shaft flange nut by turning the shaft past the flange until the bearings are seated.

Purpose of the rear axle axle oil seal

As already noted, the main role of the consumable we are considering is to ensure the tightness of the axle shaft housing. The oil seal is located directly on the axle shaft itself, so it is exposed to the rotating elements of the rear drive. The product looks like a regular rubber O-ring, which tends to lose elasticity over time, resulting in an inability to prevent lubricant leakage.

Finding out about oil seal failure is very easy. There will be traces of grease at the installation site. To do this, the owner should look into the area where the rear hubs are located.

Replacing the axle shaft seal itself is not a complicated procedure, although it is quite labor-intensive because it involves dismantling not only the wheels, but also the hubs. The cost of new oil seals will not upset the owner, since it will not exceed 150 rubles. for a unit.

Important! Before purchasing, we recommend paying attention to two aspects: the internal and external diameter of the product.

Even a difference of 1 mm is unacceptable, since such an oil seal installed on a UAZ Patriot is guaranteed to cause an oil leak. This means that the procedure will need to be repeated. Therefore, we take measures to avoid this annoying moment and carefully study the dimensions of the required product.

We are not talking about oil seal repair, since this category of parts is not subject to such action. The only option is to replace the axle shaft seal.

Next, we’ll take a closer look at how to properly replace the rear hub oil seal.

How to disable the immobilizer on a UAZ Patriot

Removing the steering knuckle of the UAZ Patriot

DIY replacement

Let us remind you that this procedure should be resorted to if the owner of a UAZ Patriot discovers a leak in the area where the rear hubs are located.

The procedure is as follows:

1. We place the car on a level area. We use a jack to hang one of the sides of the stern of the UAZ Patriot. We install a “safety net” under the bottom.
2. We dismantle the wheel, loosening its fasteners even before raising the SUV.
3. We drain the lubricant that is present in the bridge body.
4. We see the hub flange, which is fixed to it with 10 bolts. We unscrew them.
5. The next step will be to remove the axle shaft from engagement with the differential gears in the UAZ Patriot gearbox. If the axle shaft “resists” the output, then do this:

• take the brake drum and turn it with its back side towards the assembly;
• We screw two bolts into the holes on the drum body (they are connected to the axle shaft);
• Having attached such a structure to the end of the axle shaft, we pull it towards ourselves, then rejoice in victory.

1. Now you have to unscrew the lock nut. After this, we dismantle the figured washer.
2. We proceed to unscrew the main nut and remove the second washer, after which we dismantle the outer bearing.
3. Access to the hub is open, so we remove it.
4. We remove the worn oil seal. For this purpose, we use pliers paired with a screwdriver.
5. Having removed the seal, we find the bearing. It is recommended to check it for the absence of play, noise during rotation, as well as the presence of visible mechanical damage on the surface. If unsmooth rotation or the presence of play is detected, then the bearing is “sentenced” to replacement. The replacement procedure involves removing the element from the axle shaft. For this you need a suitable puller.
6. After dismantling the UAZ Patriot oil seal, we clean its seat.
7. We take a new element, lubricate its surface with “Litol 24” and install it, avoiding distortions. To press the oil seal in, use a special wrench. If it is missing, then a tube of the appropriate diameter will do.
8. Alternatively, you can use a worn oil seal as a mandrel, turning it over with its back side.
9. When the replacement of the axle shaft seal is completed, we assemble all previously dismantled parts.

Attention! Do not forget to fill in new lubricant in the required quantity.
