Re: Need ideas. 15yr old vibration that just won't go away

Sounds like you've checked almost everything that a smart person would check.

Two silly questions:
1) Is it possible that the noise is coming from tire rub? You mentioned it's lowered and the problem only happens during acceleration. (and a real stretch, but are any parts of the drive shaft rubbing against any parts of the body or frame or exhaust?)

2) Is the exhaust system stock? Plenty of room around it, nothing near the frame or body or tires?
