Hi Tim, Good questions...

The vibration usually appears at approx 1800 RMP in 4th gear and varies with the engine load. This would transfer to a constant driveline rotational speed I believe.

The vibration is most prevelant in mild accel/decel. Hard accel/decel reduces the vibration. If I "float" the engine speed exactly with the road speed - ie unload the driveline - the vibration stops. Also stops when I push in the clutch.

No strange sounds at this time but this is a pretty new vibration. Whatever's wrong isn't too bad yet.

How could an exhaust hanger cause this problem? That's a new idea no one has suggested.

I concur that I should inspect the guibo. In my 2002 days, it was obvious when the guibo went because of the crunching noises of the flanges hitting. (and I replaced quite a few of those things...)



: is it at a certain speed or a certain RPM? Are you SURE it's not just an exhaust hanger? Check that out for sure... Is it only coming from the stick, or can you hear a sound somewhere? I think you can check out at least the Guibo, I'd give that a look, that's at the end of the tranny...

: Tim
