went to see it yesterday. The posi was shot as best I could tell. we had the cover off the unit just to look at it and it looked fine inside. We then took a breaker bar at the drums to test the posi (put breaker bar on each side between drums and eahc guy put pressure in the opisit direction) to see if it would "hold under some pressure it held for a split second and then turned (opposit directions) Put about 40lb of force on the braker. After that I could hold the drum on my side and the other guy could turn his side. That would tell me that the rear is junk right?
