About a month ago I had my rear drivers side wheel bearing replaced by a mechanic. Since then I have put close to 2K miles without any issues. All of a sudden yesterday, I start hearing a whooshing noise like I had something in my rear tire. It would come and go under 40MPH, but the faster I went it would disappear. A couple minutes later, everytime I went to stop, I would hear a loud knocking noise in the rear. The noise only occured when I pressed the brake and the knocking frequency was dependent on speed. If I released the brake during deceleration, the noise would disappear. The noise would not occur during acceleration.

I jacked up the car, did the old wheel shake test. I inspected the suspension, the sway bar endlinks, brakes, anything loose or broken. Nothing looked wrong.

I'm taking it back to my mechanic tomorrow. If it turns out to be the wheel bearing, it should be covered under their shop warranty. It got me thinking though, what else could it be?

 

Lol depends on how much junk you got in your trunk?. Ha ha.
I think it sounds more like they put a bad wheel bearing in or they did a horrible job with the install.
Hope it all works out for the best!

 

At first I thought it was something rolling aroud in the trunk lol. Anyway, I just got a call back from my mechanic and turns out the caliper was sticking. They cleaned and greased it up for me free of charge.

 

Sweet good to hear it was something easy
