i read alot of posts on the subject and still have the vibration. the vibe comes in at about 2800ish rpm and goes away above 3000 rpm in 4th gear and still remains in 5th but not as noticable. 1st thru 3rd no vibe. adjusted the u-jiont operating angles to within .5 degree although the pinion may be a little low. hate to bring up an old topic but i need help.
