Cars are equipped with front wheel bearings and rear wheel bearings. In fact, any machine with moving wheels is likely going to have wheel bearings. In vehicles, wheel bearings reduce the amount of friction in the spinning wheels. Otherwise, if you were to have a lot of friction, there would be a lot of heat generated in the wheels and tires of the vehicle. Wheel bearings will reduce this heat by serving as a lubricant for your wheels and tires. You will find these wheel bearings installed in the drive axle of each wheel and in the steering assembly. In most cases, the wheel bearings will stay good for several years, depending on how often you drive your vehicle.
However, wheel bearings do start to go bad when they lose their ability to lubricate the wheels and tires. If this were to happen, then your wheels and tires would generate a lot more heat than normal. Not only that, the rotation of your wheels and tires would not be so smooth anymore. You will notice a lot of disturbing symptoms coming from your entire steering assembly. These are symptoms that you should not ignore because they will only get worse as time goes on.

The Top 5 Symptoms
Below are the top 5 symptoms associated with bad front wheel bearings and rear wheel bearings.
1) Shakiness – If the wheel bearings are damaged then you are going to experience a lot of shakiness and vibrations coming from your wheels as you’re driving. This is due to the wheels having more friction which causes them to move out of place. This shakiness will only get worse if the wheel bearings are not replaced.
2) Inconsistent Movement – You may be driving along one day and find that your car will suddenly slow down on its own. This is due to the wheel bearings being worn out or defective. They are not allowing your wheels to move smoothly anymore, so the movements of the wheel are slowing down. If you let this problem continue, it will eventually lead to the wheels not moving whatsoever. This means the car won’t move and you will be stuck until you replace the bearings which are causing the issue.
3) Grinding Noises – When you don’t have good wheel bearings to serve as a lubricant for the wheels and tires, there is going to be a lot of metal making contact with other metal. This will not only cause too much friction, but it will generate too many grinding noises. These grinding noises will only get louder and louder as you drive faster.
4) Tire Wear – The more you drive with bad wheel bearings in your steering assembly, the more your tires will become worn. However, the tires will be unevenly worn which is actually quite unusual. All four tires are supposed to be evenly aligned on the ground which means they should all be getting evenly worn. But since bad wheel bearings cause alignment issues, the tires become unevenly worn. The tire that has the most wear is usually the one that has the bad wheel bearing which needs to be replaced.
5) Steering Wheel Vibrations – When you have shakiness coming from the wheels, then you are bound to feel vibrations in the steering wheel as you’re holding it. But rather than feeling the vibrations at higher speeds like when the tires are unbalanced, you will feel the vibrations at slower speeds when it is a wheel bearing issue. Eventually, the vibrations will get worse as time goes on and they will get worse as you accelerate. You’ll obviously want to replace the bad wheel bearings before it gets to this point.
