Differential fluid?

[wrenchin hobo]

Anyone remember what gear oil weight is used in these things?
It's been too long since I've done one and didn't want to buy the wrong stuff.

Thx guys

For the differential fluid use 75W140 synthetic gear oil. I recommend Mobil 1.

Glad I asked, for some reason I was thinking 75W 90
maybe that's what the mopar cars take.

Thanks

If you have the ELSD in there, make sure you either add the friction modifier or use a synthetic lube (no modifier needed with synthetics - it's already in there). My preference is Royal Purple , though Mobil 1 is good as well.
