Sup, finally gettin my car fixed tomarrow, but after sitting for so long i saw that it dropped all the differntial oil, so my question for you guys today is what kind/ how much differntial oil do i need? Thanks

 

top it of with 85 90 gr oil, when you fill it up itll start to pour out of the same whole you fill it up with( on the passanger side above the axel tube ) once it pours out the of the fill its full,, did u understand lol.

use a 3/8 drive and extension to get it out, small extension
and some black silicon around your plug threads to seal it up.

 

Alright thanks man. How much will the oil cost? Is it sold by quarts?

The mechanic installing my fuel pump is gonna change the differential oil so its all good, no need for explinations

 

I'd get 2 quarts of Mobil 1 Gear lube 75-90 and one bottle of the differential additive from GM or your rear end will be making noises
