it ended up being the main pinion gear, so i repaced my rear drum to drum last weekend it runs again now thank god.. thanks for the imput

should your truck be in gear or in nuetral in order to check for slop in drive shaft?

i think i need to replace my rear differential, a couple of months ago my truck started to make a knocking sound from the rear now its so loud i know its gonna go any day now my question is the knocking seems to go away when i press in the clutch and then when i let off the clutch its start banging, any idea what is causing that and will replacing the whole rear fix it, i put it up on jack stands and put my ear right on the rear differential and i could definatly hear the knocking inside..
