I have a 68-70 B-body Dana 60 axle housing that was raced and spent some time under a Camaro. I'm building it to put under my 69 road runner.

When I installed my D60 narrowing fixture I found that one of the tubes is bent such that the bearing housing is about 1/8" out of alignment with the carrier bearings. I heated and quenched the tube but this had zero effect. The next attempt will involve the careful use of a press to straighten it.

Question: is there a tolerance associated with axle housing straightness? Or does any amount of misalignment cause excessive bearing and tire wear, unacceptable axle shaft sideloads, and a car that tracks or launches poorly?

Thanks!
