knocking noise
Hey, I have been hearing a "knocking" (tapping) noise that seems to be coming from the left front tire area. Or at least that seems to be the area. When I idle no noise. As I drive I hear it and the faster I go the faster the knocking is. I took it to my mechanic and he has no clue! He put it on the hoist and rotated the tires....still knocking. He has no idea what it is and told me to drive it for a "week or three" and if it gets worse let him know. Does anyone have any idea what this could be? The mechanic doesn't think it's the wheel bearing, not sure if he even checked it. I have a 2006 HHR. If anyone could come up with something plz let me know. We are going to take it to the chevy dealer next week.

I would suggest having your mechanic inspect the CV Joint on the Axle Shaft closest to the wheel. You might have a torn or ripped CV Boot, which could have allowed road debris and moisture in. The CV Joint may be going back, especially if it is always knocking when you are turning.

I may be wrong but I think you guys may be misinterpreting what the OP means. In this case when they say when the wheel is turning I think they mean when the wheel is rotating.
Not knowing what kind of tapping/knocking this noise is makes me wonder if something could be stuck in the tire.
