Do a thorough job cleaning all the old fluid out. There is a shelf of sorts on the bottom of the differential housing when you crack the cover. This shelf retains quite a bit of fluid. Make sure you get all the old contaminated fluid out.

ok someone please help me today I'm changing my diff oil with advance autoparts 75w-90 syn oil to just flush the diff because its the only one with out LS (which is limited slip)in that vescosiuty but when i look for the 75-140 ( the one i need) syn oil they all say "LS" is it ok for me to put LS oil in a NON-LS diff???? I'm going to change to to a good brand but they all say LS?? help I'm only doing 75-90 to flush the diff and because I'm not sure about the LS oil in a NON LS
honestly i think it won't make a difference because the LS oil if for the clutches and since mine doesn't have the clutches it should be fine but i just want to double check before i get good oil.
