What is the rear hub bearing, how it is arranged and how to replace it?

The running system performs many functions, the main one of which is to ensure the controllability of the car. To the car was maneuverable and safe, it is equipped with a special turning fist and a hub between the axles. To ensure that they are as reliable as possible, they consist of two bearings. Both parts can differ in size and cost, but their design remains unchanged. Both the front and back parts have a conical shape. Although some motorists claim that the rear hub bearing is easier to operate than the front. To finally find out the answer to this question, in today's article we will consider all the features of this detail.

First, let's look at the design of this element. As we have already explained, the rear hub bearing has a conical shape. So - it is attached to the axis with a special thrust nut or washer. The more this part is tightened, the more tightly the rollers will be pressed. Due to this, it is possible to exclude the possibility of a backlash mechanism.

So why is the rear hub bearing easier to operate?

The design of the front and back parts are very similar, but there are differences. The fact is that the rear hub bearing does not have a pivot, so it is easier to operate. Now several types of these parts are installed on cars:

• Radial ball bearings (most often for vehicles with dependent suspension);
• Conical (for independent).

The first mechanisms differ from the second ones in that they do not have the possibility of adjusting the degree to which the rollers are pressed against the clips. They cost much less, and you can buy them absolutely in any town.

Why does the rear hub bearing fail?

It often happens that this part is out of order because of the road dust that has got into its body. This can happen because of leaked oil, but more often than not it happens because of water hitting the hub. Well, no one is insured against a run on a puddle. So it turns out that the best thing to have in your trunk is a couple of such details, so that at some point you can not go home on the tow truck. But to have a set of new parts with you is still half the battle. You still need to know how to change the rear hub bearing. Therefore, below we give a small instruction for removing and installing this part.

Replacement of the rear wheel hub bearing - step by step process

First remove the protective cap of the hub nut and lower the tightening of the wheel bolts and the mechanism itself. After that, take the jack and lift the car for 5-10 centimeters. In this case, do not forget about additional supports. Next, turn on the first gear and put the substrates under the front wheels. Then remove the wheel, brake drum and pads. Then, using a puller, we remove the hub from the journal and the inner ring of the bearing. The next step is the removal of the lock ring and then the bearing itself. All the mechanisms are thoroughly washed, and a new part is pressed into the hub. The rear hub bearing is installed in the reverse order.
