- ABS light
Identifying a wheel bearing noiseWatch
- Drive the vehicle to confirm a wheel bearing noise is heard, make sure to test drive at both slow speeds and highway speeds
- Check for a constant growling or groaning type sound that usually gets louder the faster the vehicles speed
Tip : Uneven or chopped tire wear can sometimes mimic wheel bearing noise, check for even tire wear before condemning noise as a faulty wheel bearing
Pinpoint noisy wheel bearing locationWatch
Time required: 5 minutes
Tools Required: None
- Locate a smooth road with minimal traffic and remove or turn off noises such as the blower motor or radio
- Bring the vehicle up to the speed the noise is most noticeable
- Slightly turn the wheel back and forth, enough to shift the weight of the vehicle from side to side
- Listen for the noise to change and note which direction the noise sounds the loudest
Tip : Generally, which ever direction you are turning that the wheel bearing sounds the loudest, the opposite side wheel bearing is the issue. Example, if it is loudest turning left, then usually the right wheel bearing is the faulty one.
Checking wheel bearing for play or loosenessWatch
Time required: 15 minutes
Tools Required: Floor jack, Jack Stands
- Safely lift vehicle of the ground, if using a floor jack make sure to secure with jack stands!
- Grab the tire at the 12 o’clock and 6 o’clock positions. Shake the tire in and out while feeling for any play in the wheel bearing. If looseness is felt the wheel bearing is faulty and will require
Tip: If play is felt in the tire, make sure that it is not coming from a loose suspension component like a ball joint or control arm bushing
Free spin wheel bearing to confirm noiseWatch
Time required: 15 minutes
Tools Required: Floor jack, Jack Stands, Stethoscope
- With vehicle in park/neutral, start the engine to allow engine vacuum to release the IWE actuator (DO NOT PUT THE VEHICLE IN GEAR)
- With the help of an assistant spin the tire by hand while listening to the wheel bearing. Due to the noise of engine running, a stethoscope may be needed to hear if the bearing is noisy.
- If the noise is confirmed, the wheel bearing will need to be replaced.
Tip: If a ratcheting or clicking sound is heard, it may be caused by a faulty IWE actuator
