So I went and picked up my car today from the shop after getting new shoes, wheel cylinders, and ball joints all around the front. I'm driving it home and I run over a small bump and I hear a grinding noise in my front driver side tire. Any idea on what that would be? It would do it for a little bit and then stop, but it was making me nervous.

 

Not sure if it helps but the tires are a bit low and do need air, any ideas would be greatly appreciated. Thanks!

 

sounds like the tire was rubbing on the wheel well

 

One other thought. If they relaced the wheels cylinders, maybe a spring or bracket in your braking system has popped loose or shifted.

That's what I'm afraid of. I'm going to have to get it looked at I don't like the sound of it and I don't want my wheel falling off...sigh...
