I was wondering if anyone knows how much oil goes into the rear axle and what kind, it doesn,t say in the manual and it looks like it's been leaking for a while, I know you fill it up to the drain plug, but that doesn't tell me how much to buy or what kind
no noise , car has 126K on it and I just change the transmission fluid and filter, notice rear axle has very small leak so i check the fill hole and I can,t see or feel with my finger as far as tip of finger to first knuckle but I put a small stick in it and it has some oil in it, so I will pump whats inside and refill, but how many Qts go in it and what kind is what I need to know, I know you fill to the fill hole but that does not tell me how many Qts to buy.
ok u will need one bottle of SAE 80W-90 GL-5 Gear. u can get Castrol brand in auto zone also if it's have small leak, stop leak will help (but not if its big leak!!!) get also Additive - stop leak its in blue tube called "TransX posi-trac" it will also make differential quiet . u need to pump out all old oil, best it's to use garage air compressor brake fluid pump system (like i have) but u can use hand pump, just stick thin hose in refilling hole (where u previously removed bolt) just make sure hose went alway down!!! but u need to do it on hot so drive on highway for about 10 miles.
pump it out, when u refiling add Additive first then gear oil, as soon as oil start to come out from plug hole u fine (its mean level is normal) so just put bolt plug back and u DONE
