The wheel bearings of your car take a lot of abuse. They support the entire weight of the car when it’s running. That aside, the wheel bearings have to shoulder extra pressure while negotiating bad roads and the occasional curb, when the lateral force on the corners makes your wheels spin thousands of revolutions each minute.

Wheel bearings, unlike its engine counterparts, don’t get a constant supply of lubricating oils. Bad wheel bearing symptoms may come up once in a while, and as a car owner, you have to tackle them.

Some common Bad Wheel Bearing Symptoms

Here are some symptoms indicating that you may need a wheel bearing replacement:

1. Snapping Sound

A snapping, popping, or clicking sound indicates that you are driving with a bad wheel bearing. It means that the outer CV-joint of the wheel is damaged or worn out. But such sounds may also indicate inadequate clamping or excessive bearing endplay. The noise is usually heard while taking a sharp turn.

2. Grinding

This typically means there’s mechanical damage to a wheel-end system. It could mean a loss of integrity like raceway or roller damage. The grinding noise comes when there is a shift in the load or while taking a turn.

3. Clunking or Knocking

A knocking or clunking noise means that the U-joints or CV-joints are overworked. The noise is usually caused by a backlash in differential gears, and may not indicate worn out wheel bearing symptoms. It’s normally heard while changing directions or changing gears.

4. Rumbling or Growling

Faulty electrical, tires or drivetrain components may cause these sounds. For defective wheel symptoms, the vibration is emitted while driving straight at a constant speed. The noise increases while turning the steering wheel to the right or left. The rumbling noise comes from opposite of the side which is defective.

5. Wobbling

Worn out tires often cause wheel vibration or wobbling. It indicates a major misalignment in the wheel or suspension. It’s one of the most definitive bad wheel bearing symptoms and among the earliest signs of an extreme mechanical damage. Wheel vibrations can also happen if the lug nuts aren’t properly torqued.

6. Shuddering

Vibrations at constant speed are usually associated with damaged or worn out suspension or a misbalanced suspension system. It indicates a damage on the wheel bearing or hub.

7. Abnormal Side Pull

A defective equalizer or caliper will lead to an abnormal side pull when the brakes of the car are applied. But it may also indicate worn rotors or brakes. Excessive run out can also lead to loose bearings causing the brakes to pull or pulsate. The common cause, however, is a warped rotor because of the break caliper not retreating.

8. Uneven Rotor

A defective caliper or a bad equalizer usually causes an uneven rotor or brake pad wear. This is not exactly bearing-related. Excessive runouts may lead to uneven wear and tear of the rotor and brake pads. Non-retraction of the caliper is one of the common causes of a warped rotor.

9. Abnormal Tire Wear

There could be several causes for an abnormal wearing of the tire. Misalignment, damaged suspension components, and improper inflation lead to tire wear. While extreme wheel bearing looseness or wear could lead to abnormal worn out tires, it’s usually related to various other failures.

10. ABS Failure

In some extreme cases, external or internal sensors of a wheel could be damaged because of the excessive movement from too much endplay. ABS failure results from a major mechanical damage. In brake systems where the sensor is externally mounted, corrosion could lead to damage.

Fixing Bad Wheel Bearings

We all know what can happen with a bad wheel bearing. Whenever it happens, the bearing needs a replacement. And it’s always advisable to get an authorized mechanic to handle it.

A wheel bearing, no matter how bad the condition is, don’t fail immediately. You have to carefully notice the bad wheel bearing symptoms. The bearings typically give a car owner some time before they call for a replacement. When a wheel bearing fails completely, it may lock up and prevent your car from moving. Driving with a noisy bearing also causes the sound to grow louder. Observe the faulty wheel bearing symptoms and replace them before the problem compounds.

You may not really need to replace the wheel bearings on both sides. Just because one has failed, there’s no reason to believe that the other bearings too will need a replacement. Wheel bearings of a car usually last a lifetime.

Final Thoughts

As already said, replacing bad wheel bearings is quite expensive, largely because of the labor charges involved. Don’t try to do it yourself. There are innumerable parts to remove before you can actually get to the car’s wheel bearing, particularly in an all-wheel-drive or a front-wheel drive vehicle.

Also, you won’t have the necessary equipment to work on it. Getting a bearing in and out of the hub, sans a press, is a difficult job. Replacing the whole hub and the bearing as one unit is easier and most mechanics prefer to do it that way.

Remember, the first bad wheel bearing symptoms should prompt you to take your car for servicing. Ignoring the symptoms could lead to greater damage in the future.
