Well since the Z was new ive had a popping sound coming from the tops of the rear shock mounts. It has increasingly gotten worse and I had it written up on monday when I dropped the car off for the brakes. Has anyone else had any trouble with this?
No, I have not heard of this condition, and after a preliminary document search, there is nothing in the GM database as of this time.
Personally, I have not ever had an issue like this, so you may have a loose mount or stud.
Please keep us posted on the resolution to this issue, as I am interested, thank you, c4c5
