Well, the third member and axle we given to me separate. The axle is like brand new and it has new shafts, brakes (wheel cylinders, shoes, springs, etc), bearings, and other goodies. The third member was given as a separate part (not bolted to the axle). It's a low mileage piece and it's in great shape. The tag was missing for one reason b/c it only had 3 nuts holding on the old gasket. I would figure out by doing a burn out if the axle was on the car (hint: I said it was on stands). I already reassembled it, put a new gasket and sealer on, and torqued it down. I added SOME gear oil to for now, until I get ready to hook it up (I've been having to pick it up and move it myself). Is there any other way to tell besides taking it apart or doing a burn out LOL. If I do have to take it apart, what specifically do I look for (like looking for clutches or what)?
