Detect defective wheel bearings in the car
How can you tell when a wheel bearing is defective? Symptoms, consequences & testing
The task of the wheel bearings in the car is to let the wheel roll on the axle. Defects in the wheel bearing can arise with increasing age and use of the car. When driving regularly through tight bends and on curbs, wheel bearings are subject to high stresses and wear and tear occurs. Often the driver of the vehicle does not immediately notice the defect in the wheel bearing. In the worst case, this can result in expensive consequential damage.
Learn how to recognize a defective wheel bearing, what changes in the behavior of the car and what can happen if the bearing is defective. Find out now about the prices for changing the broken wheel bearing at workshops in your area. At FairGarage you can compare prices quickly and without obligation and book appointments online.

Defective wheel bearing - what can happen?
A broken wheel bearing does not always mean that you can no longer drive your car. Even if the bearing has been defective for a long time, the car can still be roadworthy. Over time, the signs of a broken wheel bearing get bigger and bigger. The noise level is getting louder and louder and is increasingly annoying when driving. A defective wheel bearing that often makes unpleasant noises gives you an uncomfortable feeling, especially when you drive quickly around bends. Furthermore, a damaged wheel bearing can become wedged and thus make it impossible to continue driving. In addition, the affected wheel begins to tremble badly over time, and control of the car, especially in tricky situations, is then only possible to a limited extent.
Consequences of a broken wheel bearing
What can happen if the wheel bearing is broken? The consequences can be varied. The defective wheel bearing, for example, gets very hot. This is always dangerous as the overheated bearing can start to burn the grease contained in the wheel bearing for lubrication. This is particularly spectacular with trucks, truck semitrailers and trailers. Whole trucks have burned down just because a single wheel bearing was broken and the fat burned off. The costs that result from this are understandably many times higher than a professional repair.
What can happen in extreme cases?
It becomes dangerous if you simply ignore the defective wheel bearing in cold blood and want to continue driving.Really bad: The affected wheel blocks or even tears off. Of course, you shouldn't let it get that far.
How do I recognize a defective wheel bearing?
Not much happens at the beginning of a defect. It cannot be seen from the outside either, as the wheel bearing is covered by the wheel itself. The sign of increased fuel consumption is also not always noticeable. However, after a while, damage to the wheel bearing becomes noticeable through noise. Broken wheel bearings cause unnatural and creaking noises while driving.
Defective wheel bearing: recognize the noise
Noise is the first sign that the wheel bearing is broken. Think of the thud as if heavy marbles roll back and forth in a thick-walled saucepan. The noise can be localized fairly precisely. If the noise only occurs when cornering, the damage is still "young". Bollert and grind it even when driving straight ahead, you should not continue driving - at most as far as a workshop.
Other symptoms of a broken wheel bearing:
- Skewing when braking
- A changed steering feel
The symptoms mentioned here are quite clear. It is bad if your vehicle comes to a standstill sooner when it approaches a traffic light than it did before. Such symptoms, which occur individually or together, require an appointment in a specialist workshop as soon as possible.
Assign the signs of the defect
In order to be able to determine which wheel bearing is broken, it is first necessary to locate the side from which a suspicious noise is coming. There are two situations for this: Checking the wheel bearings while driving or checking the wheel bearings on a jacked-up car.
Check defective wheel bearings while driving
If the sound described sounds when driving in a right-hand bend, the left wheel bearing is often defective. The check of the right side takes place in the same way as that of the left side. If you drive a left turn and the noise occurs, then the right wheel bearing is often defective. In the case of an advanced defect, driving through an empty tunnel can also help. With the windows down, the hall that the tunnel walls throw back can be helpful in locating the affected side of the defective wheel bearing. However, this is not sufficient for an exact diagnosis.
Jack up the car to check the wheel bearings
Another way to identify the defect is to jack up the vehicle with a jack. The so-called wheel bearing play can be checked on a free-floating wheel. To do this, grip the bike firmly with both hands and test it by moving in opposite directions. A defective wheel bearing or too much wheel bearing play feels as if the rim is not screwed tightly enough onto the wheel hub.
Reliably check wheel bearings in the workshop
When doing a self-test of the wheel bearing, it is not always possible to reliably say whether the wheel bearing is OK or whether it is damaged. However, if the noise does not occur with any of the methods described here, a broken wheel bearing is rather unlikely. If the noise you initially noticed occurs again at a different point in time, the problem is probably different. Only a check in the workshop can provide a reliable answer here.
