| | Rear vibration when car cold.
Whenever I start my car first thing in the morning or in the afternoon, there is an obnoxious noise coming from the rear passenger side. Here is what I have tried:
1. I have tightened up every nut and screw that I could find back there.
2. Removed my spare tire and jack.
3. Crawled underneath car and checked exhaust hangars/heat shield above exhaust. Both are tight.
If I press the throttle so the rpms go over 1000, or once the car has warmed up, the noise goes away. What else can I check?
