Clicking/Knocking.. Driver side rear wheel

Chris04Z4 · 05-12-2010, 09:19 AM

posted this in suspension/braking section but the problem might now be in this area.... need some help.

Ok..... for about 6 months now this has been going on... and off.

-Clicking that is Speed related.
-Usually under accel or heavy braking... 95% of the time... i dont think i have heard it while just rolling but i cant remember really if i have.
-It can be loud sometimes and other times can barely hear.

ITS NOT my ebrake assembly that could be broken in the hub rattling around.. i removed that...

ITS NOT a pebble or rock in the tread... or a nail in the tire

Going over bumps does not cause it...

I will hear it one minute... the next minute i wont.

I thought it was the ebrake cable rubbing on the rotor from when i removed the assembly so i pulled the cable out... put about 2500mi on the car and never heard it.... so i can go a full month and not hear it.... but it just started back today.

I think its in the axle but i really dont know.... the axle boot has no holes or rips... everything physically checks out under the car and looks ok with the exception of my bushing is cracked for the diff mount.... but that should not be causing this lol

Maybe the TPMS bracket got loose? Or wheel balancing issue?
