on a 1999 jeep cherokee 4.0 liter 6 cyl.i know for the rear end.and front end. that you use sae 75w-90 gear lubricant.it a 4wheel drive. but what do you use in transfer case.i’am thinking transmission fluid is i’am right.
The owner’s manual should tell you what to use in the transfer case.
ATF is a good bet…but you MUST check your owners manual.
