Thread: rear axle alignment

Tweet

Im ready to finally put my rear end in for good. What kinda things can I do to make sure it is straight and sitting perfectly on my leafs? also I did a test fit of my trac bars and noticed one of the snubbers is touching when its sitting down and the other side is about an inch away......any ideas?

yeah, if this is a Chevy rear, I have an idea that one of the axle housing tubes has rotated in the third member housing. I was talking to one of the racers at Firebird one night that this had happened to. He just couldn't get the car sorted out to go straight and finally found a rotated tube. He re-indexed it and welded both tubes at the housing and cured the problem.

shit, well how can I make sure my rear end is square?

the best way is put it on a 4 wheel alignment machine, but if you cant do that pull a string on it.

I square up my rear with a Cheapo Depot laser level. Just index to the metal rim or to the brake hats, axle ends or whatever as long as you flip the level over from side to side. Drop some points from the frame or body to develop a centerline for the chassis and then measure out to each side with a tape from the center by shooting the laser to the tape.

PS, Start by finding a chassis centerline then center the rear housing and then align it to the tapes up front.

I realize that this isn't the same measurement accuracy as factory but better than factory is good, isn't it?
