Picked up the car tonight and went for a short drive. I am glad to report that the replacement bushings made a significant improvment in reducing the vibration/drone.
I was able to replicate the vibration/drone in a few instances, but now minor and nothing to the extent from before the fix, i.e. it only lasted a few seconds versus being constant.
The Bulletin for this work mentioned in my previous post is for MY 2011, V6 with auto, and VIN past B9145905. Maybe someone knows about a change past that VIN number?
Am undecided at this point if the condition is still an issue to me.....am currently hyper-sensitive to any vibration/drone because I have lived with it for the past year, along with the frustration of waiting for a fix. The absence of help from the GM monitors to this board (not even a reply to PM) along with the deletion of threads, and fellow member being deemed a troll for posting about this issue still bug. Those of you with this vibration problem can probably relate.
I still luv this car..... it's looks turn heads...and I still find myself looking back at it after I park and walk away. Am still hooked on how the original Camaro design was blended into a modern car (always grin when turning the radio AM dial
).
Will do some more driving this weekend to see how much of the issue still exists when not specifically trying to replicate the problem.
