Bruce,
I don't know much about this rear other than whomever put it together forgot to put the copper washers on each stud, so the rear constantly had a drip. I can tell you that it does not spin both tires, yet balances power very well on a dyno-pak dyno. I was recommended to put 75-140
Amsoil lube in it.....
The reason I tell you all of this is that could it be that I have a posi rear with no posi lube in it? If so, I assume that it will not work without it.
Help!!
