Thread: If worn out wheel bearing

 
Unfortunately, during operation of the vehicle is not yet managed to avoid damage some components and wear of individual parts. In our conditions, when disgusting as roads, often suffers chassis of the vehicle. The first flying bones, then ball joints, bushings, stabilizer, etc. Rarely damaged the bearings of the hub. About them and will be discussed below.

As you know, the bearings are divided into two types: sliding and rolling. Since the bearing is located in the immediate vicinity of the wheel, it is logical that he refers to the latter. They experienced the load is much higher than that which is necessary to maintain other automotive bearings. The most difficult thing he has when starting, stops, and while performing maneuvers at high speed. Adverse effect on the bearing and have numerous holes and bumps that are characteristic of the road of the Fatherland.
With careful manner of driving quality bearings from proven producers will serve faithfully for a long time. Their resource is designed, at least 100, 000 kilometers. But it happens that when improperly installed part fails much earlier. Also fast break and cheap bearings made in China. Frankly, purchasing automotive parts of the low price class like the lottery, because nobody can guarantee their health. Some of them fail almost immediately after installation, while others can last several years and this fact defies any logical explanation.
To understand what bearing has failed, will help a characteristic rumble, worse when accelerating. In some cases, extraneous sounds can remind tapping the wheels of the train on the arrows, and the passenger will begin to feel weak strikes on the feet. To ensure that knocks it is the bearing, it is necessary to raise the vehicle using the Jack and check for play in the wheels. However, there are rare cases when there is knock the wheels are pretty tight. Why this happens is hard to say, because each case is individual, but extraneous noise in suspension to ignore is highly undesirable.
What are the consequences of wear of the wheel bearing? In most cases the driver will simply annoy unpleasant hum, acting on the nerves. But if time does not take action, the wheel may lock at speed, and that's quite serious. In this scenario, the amount of the repair cost may increase significantly, provided that hurt your machine. Because the risk of an accident when the locking wheel is increased to almost 100%.
Replacement wheel bearing is best done in the service station, because it is necessary to press in a special holder. But many believe that it is safer to extrude its "antiquated" way. It looks as follows: the old bearing removed from the hub, in its place is new, which literally driven into the frame with a hammer. As the press used the old bearing, which produced the hits. Yes, the process is quite simple, but is it necessary to resort to this method when any service you will professionally prepare for operation within minutes?
Will not be superfluous to check the hub on the subject of production. If the spherical surface has obvious irregularities, it makes sense to replace the entire unit as a whole. The presence of production interferes with the normal rotation of the bearing, because even the slightest surface wear can be a small backlash. After completing check how much tightened the nut that secures the hub. There are cases when the mechanics don't hold out it, so the bearing is broken in a few days after the replacement. You should also check, whether incorporated in the hub grease, because in its absence the efficiency of the site will quickly come to naught.
