The car's transmission (chassis) is directly related to driving safety: a jammed, loose wheel can lead to trouble. Therefore, it is worth paying close attention to the noise that appears in the area of the front or rear wheel; which indicates a possible breakdown of the bearing, or even the hub.
Most of the cars sold today are front-wheel drive. Therefore, it is quite logical to consider ways to replace the bearing and hub on such models.
Front wheel bearing replacement
The first step is to put the car on a jack so that the problem front wheel is suspended. In addition to the jack, for safety reasons, do not forget to install an additional support. Remove the wheel and knock out the retaining clip on the hub nut. Then it is necessary to unscrew the nut with a key on "30" (it is better to take a cap). It is worth noting that it is tightly tightened, so you will need an assistant who, sitting in the cabin, will put pressure on the brake.
Next, you can remove the caliper (it is usually mounted on two nuts) along with the brake pads, and a metal boot protecting the brake disc. Now you can remove the brake disc itself and gently knock out (preferably through a wooden gasket) the hub. The next step is to remove the bearing. To do this, you need to remove the retaining rings that are on both sides with pliers with sharp noses. The bearing, or rather its old cage, is best removed with a puller. If there is none, then you can knock out the clip with a hammer and a chisel, substituting some kind of support along the axis, for example, a stump.
After removing the bearing, inspect the hub and try to put a new bearing on it. If this happens without much effort, then the hub will have to be changed. The new bearing must be driven through a wooden spacer by applying force to the inner race. Next, it remains to assemble in the reverse order.
Replacing the bearing, rear wheel hub
If the rear disc brakes are disc brakes, then it is necessary to change the bearing, the hub as described in the previous section. If the brakes are drum, then the course of action will be somewhat different. First, you also need to hang out the rear axle with a jack and remove the wheel. Next, knock down the brake drum and pull out the protective cap of the hub. Pull out the cotter pin (if present) and unscrew the nut. Remove the hub by tapping lightly with a hammer, the inner bearing race may fall out. The collar and outer bearing races (inner and outer) can now be removed.
Clean any debris from the axle before installing new bearings. First, the outer races of the new bearings are installed, then the inner ones. In this case, it is desirable to use a suitable mandrel; also do not skew. After mounting the bearings, fill the space with lithium grease.
