So I am driving, and I turn off the music let off the gas and hear a knocking sound coming from the rear left. It is in synch with the turning of the wheels. The faster you drive lets say you are going 70 it makes a thump-thump-thump-thump sound.

If you are driving 35 its thump-----thump-----thump-----thump.

Any ideas what it could be? And prices? It sounds bad thats for sure.

BUMP! I've still got problems, does anyone have the slightest idea or could refer me to someone who might know?

Bump, is this not the right forum.

I can't figure it out, maybe it is a bearing in the back left wheel well?

Rock in tire tread????? Bearing???? Warped rim????? Warped brake rotor???? Tire rubbing ?????? Caliper loose???? Worn shock???? Swaybar link bushing loose/worn????

Remove tire and take a look....

Can you feel anything with the sound? If you feel anything, it opens up a lot of options. If not, it narrows it down quite a bit. Best bet is to get under it and look .

To help diagnose the rear end noise, put the rear end up on jack stands and turn the rear wheels by hand. Can you replicate the noise/sound you are hearing and pinpoint the location? There are many possibilities.

Thanks Kenny, I wasn't really sure how to diagnose the problem. I looked around the wheel well and nothing looked out of place. Im going to try what you said and post the results.
