Drive line angle

[garvir]

my monte carlo had -6 degrees down at the trans, -2 degree down at pinion, i had a vibe, lifted the trans +4 degrees, to -2 degrees, this in turn brought the pinion a up to +2 degrees, they were both off 2 degrees buy parallel. no vibe now... this is the way bob bolles from circle track mag explains it, parellel and opposite. you probably could get away with 1 degree differance because of the car moving up and down when you are moving, so the bearing would move.



i was lucky able to put my angle finder on the ujoint caps, gave me a true reading. the trans pan is not a true reading, they are off 2 or 3 degrees. the same with pinion, no where to get a true reading except the ujoint caps. make sure the u joint is straight up and down, put you angel meter cross car to check vertical.
