My car has recently developed an exhaust vibration. It is only felt when accelerating lightly. Seems fine at idle and under hard acceleration.
The car has 200k. I haven't yet jacked it and looked underneath. I have discovered 2 items:
1. The upper mount has one small visible crack in it.
2. The rear of the exhaust shifted up and burned the bottom of the plastic bumper. I replaced the rear exhaust mount/bracket a couple of years ago with the IPD one. It looks okay. I just sprayed the bolt with PB Blaster a couple of days ago (it wouldn't budge) and will attempt to adjust the bracket ASAP.
So it appears as if I need a new upper mount at a minimum. 2 quick questions:
1. Is there anything else I should be checking out or part I might need?
2. Would a bad mount allow the exhaust shift up like it has?
Thanks for any help!
Jim
