7 1/4 to 8 3/4 rear end swap info needed

i will refer back to this thread after looking for a little bit longer online for a rear end for sale. i have one last questionÂ… what are some clear signs of a bad rear end in need of a rebuild? in other words, how can i tell if someone is trying to sell me a lemon???

Receipts on a rebuild are a great start but not a guarantee. You may try to farm out the pieces as many of us have done, but you may end up coming out of pocket for as much as a complete unit or more. I pieced together all the parts used & only bought the axles & U-bolts new but had a reputable shop inspect the Powerlok & set up the gears. It bought me some piece of mind.
