Oldsmobile/Buick Repair: 2000 Jimmy Diamond - Vibration followup, chevy lovers, rear axel


Question
Van,

I forwarded your email to the dealership and they checked everything you suggested and found all to be normal or well within specs (i.e. not at an extreme but still in-range value).  I also emailed Ed Eliassen and he suggested the following which was also normal... Driveshaft to yoke angles, driveshaft angles, and a rear trans mount shifted out of spec.  

They apparently unhooked the front driveshaft (because it is 4wd) and still found nothing.  They are at a loss, and suggest that I drive the vehicle until it gets worse so that we can find the answer at some point in the future.  They are 99.9% certian its coming from the back, and 80% certian its from the back-right.  The rear axel was also checked and was completely normal.  Any ideas before I pick it up monday afternoon?

Thanks,
DAN

Hello Dan,
If you forwarded my reply, I am curious if they agreed about the hogwash theory.
