Vibration at 80 mph! only when off the gas! Ok guys i've been putting this problem off for a few months but now that it's winter i'm gonna tackle it. I noticed this last summer that when i'd be on it past 80mph it didn't vibrate but when i let off the gas it started to vibrate BAD but then would go away if i gave it gas again. I'm assuming that it is the U-joints out. Just checkin'. And what is a good brand or will the Napa one's work good? Thanks guys~Cole~

GM balanced the driveline with it installed on the vehicle. Pull the driveline and take it to a good driveline company and have them balance it by its-self. You might as well have them install some new u-joints while you are there. I would recommend that you use a u-joint that doesn't have a grease zert, as the greaseless u-joint uses a synthetic grease that will last longer than a greaseable u-joint. They are also much stronger as well.
Both my T/A's had a bad vibration starting a about 80-85 and would go away at about 125. After 125, I never had a vibration problem all the way to 160(would have kept going but ran out of straight road where I was testing my top speed runs).
