I need to replace front, back differential fluid and transfer case fluid also.
what type of fluid those three components need? Do I need to add anti slip additive to the differentials?

Thank you

Front differential API GL 5, 75w-90 synthetic gear oil.
Transfer case - ATF +4 or equivalent.
Rear differential - API GL 5, 75w-90 synthetic gear oil.

Without the VIN we cannot tell if it has a Trac-Lok limited slip.

THE rear differential was low so I added 75w140. Is it ok to put 5w140 instead of 75w90?

Going by the VIN Dodge says you don't have Trac-Lok so no additive required. But If you bought it used, verify that as you never know if that was changed at a later date.

You don't really want to mix lubes in differentials. They are under a lot of stress and mixed lubes can cause problems.
