1999 V70T5M56 Troubleshooting Driver side rear wheel noise

Post by **abscate** » 06 Aug 2018, 09:09

Symptom - high pitch squeal from left rear wheel.

No noise on start, for first 10 minutes of driving
After 10 minutes highway speed, squeal comes on and stays
Braking does not stop or alter squeal, except hard braking
A bump in road will stop squeal for 3-4 seconds, then returns.
Swerving left and right stop squeal until car runs straight again

Possible culprits

- Rear Wheel bearing

- Brake pad squeal

- Loose parking brake components

Check your brake pads. They will sing when they get worn down to the indicator.

Bumps jars or hard braking might move the indicator away from the rotor temporarily.

No noise for the first 10 minutes because the indicator is cold, after it warms up it expands and comes in contact with the rotor.

Agree with RickHaleParker - most likely worn brake pads and wear indicators doing their job.

Other possibility is bent dust shield. Start by taking off the rear wheels and inspecting brake pads, rotors and dust shields.

Consensus is that this was a sticking rear caliper and I needlessly replaced the OEM rear wheel bearing with a Centric.

Erik insists I have race issues, I mean bearing race issues, I mean wheel bearing race issues. That was a close call. I think IA has a secret program where gnomes slip into your garage and grease your bearings at night - the only logical conclusion.

Hey I will say it again, don't be so blind to baring racism.
