Well I had a new one tonight. Putting the final touches on the new B6D so I thought I's set the slipper & diff. Tightened the diff screw and heard/felt a pop. Diff will not tighten at all now. Opened up and found the diff adjustment screw had broken. My money would have been on the plastic nut stripping but the screw broke clean at the threads for the nut. Luckily I had the ball diff from my T5M. Part numbers for the screw are the same so I was able to make it work. Anyone else had that happen? I wasn't putting that much pressure on it.
