So what is a wheel bearing?

We will explain it to you in a simple way so that you understand it. This is a set of steel balls that are held together in a metal ring, called a race. And in the center of its wheels, there is a hollow piece of metal, called a hub. However, these wheel bearings fit tightly inside this hub and are mounted on a metal axle, which helps reduce friction when the wheel turns.

Note that these are different from motor bearings, because as you may already know, there is no constant source of lubrication for the wheel bearings, and this simply means that they need to be tight enough to keep water and dirt away. road dust. And another thing is that they also support the full weight of the vehicle while driving, so they suffer a lot of abuse on bad roads, potholes and as well as lateral forces when turning.

HOW TO SAY WHICH WHEEL BEARING IS BAD TURN

It is true that wheel malfunction can endanger the safety of your vehicle. If they don’t work properly, a car is at risk of accidents. And similarly, the wheel bearings are very important for the wheels to function in harmony with the hub and the tires. You should be aware that there is a bearing for each wheel and it is very rare for all of them to be damaged at the same time. So how do you know which wheel bearing is faulty?

To answer this, the first thing to do is make sure that the bearing is actually producing the noise you hear, as this is very subtle and is best heard at lower speeds.

To identify which is bad you have to drive and be attentive to the sound. To do this, you can try gently rocking your car while driving slowly. And in case the noise decreases when you drive slowly to the right, it is possible that the damaged bearing is in the left wheel.

But if it’s less when it swings to the left, then the right wheel bearing is probably bad.

The noise of a broken wheel bearing has been noticed to sound similar to that of a dragging or buzzing brake pad. But you need to check if there is any clearance between the wheel and the part that supports it.

To remedy this, raise your vehicle with the help of a hydraulic jack and push the wheel towards you in a forward and backward motion.

In case you notice that it is not moving flexibly, then the problem is the one you are suspecting. But if not, it could be a hole in the car’s tires, suspension or steering.

Keep in mind that an uneven bearing will release more heat than a better bearing, so from time to time you may locate a good or well-used bearing by feeling your vehicle’s wheels near the fasteners. However, if one wheel is hotter than the others, then it could be a bad bearing.
