Unhealthy Wheel Bearing: Indicators and Signs It’s Time to Exchange
What Are Wheel Bearings?
Wheel bearings join a automobile’s wheels to the axles. They permit wheels to show with minimal friction. Although wheel bearings are low-maintenance elements, they’re essential security parts of a automobile’s braking, steering, and suspension methods. The one-piece hub meeting, between the drive axle and the brake disc or drums, incorporates the hub, wheel bearings, ABS (anti-lock braking system) wheel velocity sensor, and mounting flange.
The bearings are tightly packed in a grease-filled, waterproof, sealed steel ring. This housing, referred to as a race, is positioned contained in the hub, and every wheel has one. Wheel bearings have a Herculean duty: They’re engineered to assist the automobile’s total weight.
Most autos immediately use sealed hub bearing assemblies that comprise curler bearings. Whereas we don’t handle these, older automobiles used tapered curler bearings, which required servicing and preload adjusting to make sure the correct quantity of finish play or axial clearance.
Your automobile will sign that it’s time to interchange a failed wheel bearing. For instance, for those who hear uncommon appears like buzzing or clicking, then your bearing is likely to be dangerous. Be careful and pay attention for these indicators and signs:
1. Buzzing Noise
Probably the most simply identifiable and customary symptom of dangerous wheel bearings is audible. However it may be complicated. For instance, the supply of a buzzing noise could be linked to different points, reminiscent of tires and the CV joint.
2. Squealing, Growling
The everyday sounds of worn-out wheel bearings are squealing and/or growling. The sound intensifies as automobile velocity will increase. Attempt to pinpoint the placement of the noise as a result of it should determine the placement of the worn-out bearings.
3. Clicking Sound
For those who hear a clicking sound that will increase in frequency because the automobile accelerates, there may very well be an issue with the wheel hub meeting.
4. Wheel Wobble
Technicians can verify for wheel wobble by placing the automobile on a raise and manually checking for wheel motion. Usually, it will be not possible to shake the wheel and tire. Nonetheless, if it strikes, the hub meeting wants speedy consideration. The tire and wheel can actually come off the automobile at any time, at any velocity, for those who don’t restore your automobile.
5. ABS Failure
The anti-lock warning gentle might illuminate if the ring, tire, and wheel wobble, the wheel’s velocity sensor is not working correctly, and the ABS might function sporadically or in no way. See knowledgeable for restore.
6. Uneven Tire Put on
If one tire wears out quicker than the others, it may very well be an indication that the wheel bearings are worn. Nonetheless, it additionally may very well be an indication the tire is badly inflated (an excessive amount of air stress or not sufficient), the tires are improperly aligned, or the automobile has broken or worn suspension parts.
7. Car Pulls to One Facet
Worn bearings might trigger a automobile to tug to the left or proper when brakes are utilized. The course the automobile pulls alerts the place the worn bearings are positioned, on the left or proper aspect of the automobile. Nonetheless, this may additionally sign brake rotor or brake caliper issues.
8. Steering Wheel Vibration
Unhealthy wheel bearings may cause the steering wheel to vibrate. The depth will increase because the automobile velocity will increase and the automobile turns to the left or proper. Nonetheless, the vibration may very well be linked to an out-of-round tire (there may very well be a flat spot on the tire) or a tire that’s not balanced. One other trigger is broken or worn suspension parts.
9. Steering Feels Unfastened
If there may be extreme play within the steering, that means the steering appears much less responsive or much less exact than regular, worn bearings may very well be inflicting the issue.

What Occurs if You Drive on Unhealthy Wheel Bearings?
Driving with dangerous wheel bearings impacts the security of a automobile, and it may trigger a critical automobile accident. We don’t advise driving on them after they fail and advocate getting them checked out as quickly as potential. Unhealthy wheel bearings can injury issues like your hub, the automobile’s fixed velocity joint (CV joint), or the automated transmission.
“The excellent news is more often than not, a automobile will let you understand manner earlier than a failure ever occurs,” mentioned Gary Hardesty, Kelley Blue E-book’s in-house service and upkeep knowledgeable and an A.S.E. licensed grasp technician. “The secret is to take heed to your automobile. Most occasions, a failing wheel bearing will exhibit a growling kind of noise that adjustments with automobile velocity. The quicker the automobile (goes), the quicker the frequency of the growl.”

What Can Injury a Wheel Bearing?
- Potholes, tall curbs (curb bumping), and velocity bumps taken at brisk speeds can injury wheel bearings, making them particularly susceptible.
- If water, mud, highway salt, or sand will get previous the seal and touches the bearings, it should contaminate the grease, inflicting the bearings to put on down, finally resulting in failure prematurely.
- Ignoring worn-out wheel bearings can injury the automobile’s fixed velocity joint (CV joint) or automated transmission. The outer CV joint attaches the driveshaft to the wheels, and the inside CV joint connects to the transmission.
It’s essential to discover a respected service technician for recommendation to find out what subsequent it’s essential to do.
Customized Wheel and Tire Warning
One other factor: In case you are planning to customise your automobile with particular tires or rims, watch out what you do.
