Removing and installing the front wheel hub UAZ Hunter 31516

A car uses many technical elements. One of these is the wheel bearing. UAZ is also equipped with it. This is an integral part of any car. After all, it is this bearing that ensures smooth rotation of the drive and driven wheels around the axis. This node is experiencing enormous loads. Therefore, it is possible that the UAZ front wheel bearing may fall apart. What is the service life of this element, what are the signs of failure and how to replace it? All this will be discussed further in our article.

Why is this happening?

Bearing failure occurs in most cases due to lack of lubrication. It can be washed out of the clip. This happens especially often on cars that are used off-road. When crossing the next ford, water gets into not only the bridges and gearbox, but also the UAZ wheel bearing. As a result, the element runs dry. In addition, the UAZ wheel bearing fails in the presence of solid contaminants. Dust and dirt will work in the cage as an abrasive. High load is also a cause of wheel bearing failure. If the machine is frequently used on rough terrain, be prepared for an upcoming bearing replacement. Also, the element does not like large holes. Even on off-road high-profile tires, all unevenness should be handled extremely carefully. The hub bearing does not like rough driving. In addition, shocks are transmitted to other suspension elements. These are shock absorbers and silent blocks of levers (in the case of the Patriot front suspension).

How to determine wear?

Since this element interacts with the hub, breakdowns will be associated with the wheel. Determining whether a bearing is faulty is quite simple. As you move, you will hear a “dry crunch” (this is how spherical mechanisms roll). This means that the inner race is broken and the needles are spinning unevenly. Over time this sound will get stronger.

If you continue to ignore the problem, the car will begin to pull to one side. You will have to constantly grasp the steering wheel to continue moving in a straight line.

Oil seal and its features

On the UAZ Patriot, the front axle axle seals are rubber sealing rings with special springs that are involved in the sealing process. The slightest deformation of these devices leads to oil leakage.

You should also be aware that a leak through the oil seal may be caused by a clogged breather or may be caused by an excess amount of lubricant.

Currently, UAZ Patriot produces seals made of rubber and polyurethane materials. Rubber seals have a low cost (about 100 rubles per piece), but they also have a short service life. Polyurethane products have a high cost and a correspondingly long service life. But finding polyurethane seals is not so easy.

Product replacement

If you find an oil leak in the area of ​​the steering knuckle, then it is important to take measures such as replacing the seals. In this case, it is not necessary to replace the seals on both sides if the leak is observed in only one place. So, let's look at what it means to replace the front axle axle seal on a UAZ Patriot SUV.

Steering knuckle leaking

1. First, you need to place the car on a flat surface and jack up the part where the part needs to be replaced.
2. After this you need to remove the wheel.
3. The steering knuckle is being dismantled. To do this, perform the following steps:

1. the brake disc is removed;
2. the axle complete with hub, brake shield and hub coupling is dismantled;
3. the axle shaft is removed;
4. the tie rod end is disconnected from the steering knuckle;
5. The five bolt connections are unscrewed and the steering knuckle is removed.

To summarize, it is important to note the need and importance of carrying out work to replace worn seals on the UAZ Patriot. If you do not carry out repair work and do not change worn parts, this may not cause the most favorable consequences, so it is important to periodically drive into the inspection hole and contemplate the structure of your SUV from below. Thus, with the help of periodic visual inspection, it is possible to prevent adverse consequences in 60% of cases, so monitor the technical condition of your car and carry out repair work on time.

The popular Russian SUV model UAZ Bukhanka is equipped with rear and front drive axles. Although they perform the same traction functions, they have some design differences.

The main feature of the driving mechanisms is that the front axle, in addition to the bridge beam with the differential, additionally has universal joints of equal speeds at its corners with a gearbox.

Bearing replacement

So, the hub is in your hands - all that remains is to remove the old element and install the new one. To do this, take a screwdriver in your hands and remove the inner ring of the hub. We also take the last element out. Please note that to dismantle the element you will have to remove the oil seal. It is disposable and cannot be reinstalled. At the next stage, remove the thrust washer of the hub seal and unscrew the inner bearing ring.

To press out the old element, you should use a puller. Gently squeeze the antennae of the inner and outer retaining ring and pull the parts out.

Correct installation is the key to a high resource

What should I do if, after replacement, the element fails again? And not after 30, but 3 thousand kilometers? It's all about incorrect installation. This is one of the common reasons why wheel bearings fail. If you install the element at the wrong angle (diagonally), the load on the clip will increase significantly. In this case, the part will collapse within the first thousand kilometers.
