Question for you guys. I'm currently deployed in Afghanistan and I bought a b4.1. I bought the ball diff and the new bearings and when I install it the outdrives will slide left and right once it is in the tranny case. What am I doing wrong? Everything is put together right on the ball diff itself I had a experienced guy help me make sure I built it right. This is a new hobby for me and I love it, but stumped at what I am doing wrong.
