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.

This knock is always when the wheel is turning even on smooth roads.

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.

It can't be in the tire as he rotated the tires for me and the "knocking" continues. It's constant noise while I am driving....going straight or turning.

Does the noise increase or decrease with the speed of the car? I'm sorry I see now that it is speed sensitive-has to be CV or wheel hub related.
|
Thank you all. I'll have the mechanic check the CV
