centering rear end

Another possibility is something I ran into on my Cuda. The rearend housing itself is centered yet the drivers side wheel stuck out about 1/2-5/8" farther than the pass side wheel. Found out the thrust pins in the sure grip unit were worn down so much I had to crank the bearing adjuster on the pass side in a bunch to get the proper backlash. After replacing the thrust pins with a new set it's still off a little but nothing like it was. Maybe 1/4" at the very most.

The only problem with cutting off and re-welding the perches back on is the rearend should be chucked up in a narrowing jig to hold the housing straight while you weld on it. Welding creates tremendous heat and will warp a housing real easy. The only way you could do it without jigging it up is to go super super slow. Weld a 1/2" let it cool a good while, weld a 1/2" let it cool a good while. You see where I'm going.
