how to change fluid on a 10 bolt
take the diffetnital cover off, but only the bottom 3 or 4 bolts for now and let the gear oil ooze out. then take off the rest of the cover, when u fill it u need posi addtive u can find that at your local GM DEALER, i think the fill spot is on the passanger side i can't remember but DOUBLE CHECK WHERE U FILL IT.
put a oil pan under the pumpkin, pull the cover off, drain fluid and with a clean rag wipe out as much fluid and shavings as you can. put grey stuff on housing, put gasket on, pput grey stuff on cover, bolt cover on. find bolt on front passenger side of pumpkin, take bolt out, make sure car is on a levelish surface put i think 4ounces of limited slip fuild in hole then fill with desired fluid until it comes out the hole. its recommended that fluid level should not be above bottom of fill hole.
