This is bad.

^ x2 i have seen this first hand. I got a used housing from a member on here. (Clintag) that upon re assembling the rear figured out the dr side tube was tweeked about 1/8 inch out! Had to have flanges cut off & new ones welded back on with alingement bushings & bar through an empty center to square it up. Is this a (new to you) Inrearend at all?[/
The third member is. The housing is the same one that has always been in the car. As I stated earlier I was driving the car the night before. The rebuilt third member I just installed yesterday rotated fine until I installed the axles. Once the axles were tightened down I couldn't rotate the third member by hand. Something is causing pressure that is preventing the axles from rotating.
