Has there been issues with the diff catching inside the trans case? I haven’t had time to read through everything to see if it’s been brought up yet. I just built my B6.1 and everything spins freely with the diff out. But when I install the diff it starts to bind up. Its in about two spots. I think it may be the diff screw heads?, but not sure. Issue with the idler gear teeth? I’ve pulled the diff out several times and flipped it around trying to find where it’s catching. But I cannot find anything. Any help or suggestions?
