I installed a newer diffrential with 3.73 gears in my 93 auto. I have a vibration starting at around 50mph and very bad as I get closer to 70 to 80. I have turned the yoke on the drive shaft 1 hole at a time hoping to find a better balance and now have run out of options. The manual saids the companion flange that the yoke bolts on sometimes need to be rotated to acheive balance but removing it to turn it requires resetting the pinion. Has anyone had and solved this problem. There was no vibration with the original diffrential.
