I had a shop install new pads and rotors on my car the other day. Now when I drive I hear a knocking that sounds like its coming from the front. I can only hear it when I'm doing between 5-30mph otherwise the road noise overpowers it. Anyone else have an issue like this? I'm thinking they just over torqued something maybe.

 

Hmm...knocking...weird.

 

+1 on the knocking very wierd. Squeaks are usually the shims but knocking you got me their.

 

Ya its almost like a knuckle cracking sound. But not as sharp and more subtle. As if something were knocking on the inside of the fender. It fluctuates with speed. The steering doesn't seem any different and the car isn't pulling. I'm not sure which side its coming from yet. I'm stumped

I know there's a TSB for a noise when going over a bump, but this happens when driving on a flat surface.

 

Return the car, and have it done again properly.
