calm doen, its only a comercial....


just done mine last week..


undo the 4 bolts which hold the diff hangar to the boot floor cross member with a trolley jack under the diff to carry the weight. undo the 2 x 17mm head bolts in the back of the hangar which bolt it to the diff back plate and remove the hangar.

drop the diff down on the trolley jack untill the beam supports its weight - it should be facing down at around 20 degrees. using a T50 torx bit remove the 10 bolts around the back plate and knock it with a rubber mallet to break the seal and allow the oil to run into a suitable catch tray. wipe out he bootom and clean as much of the fillings off the magnet in the filler as possible.

smear a thin bead of silicone around the back plate afeter cleaning both faces with some contact cleaner and fit it back up and fill with 1 litre of 75W90 fully syn gear oil. hth
