I noticed the TSB for the rear end rattle and the vibration at certain RPMs.. i think ive got those problems cause they RPM levels that the TSB mentions is exactly where mine occur. I was wondering what was the cause of theproblem.

Ive noticed that most of the TSB elaborate on what the problem is but here on the site the TSB's are listed as the problem only. Anyone take their car in for either the rear end rattle or the RPM specific exhause vibrations? What did they fix?

 

I had vibration at 1500 rpms. they installed the damper per the TSB. It didnt resolve it all. I also noticed if I turn of O/D it vibrates much less at 1500. Go figure.
