Re: DIY- 2011 Differential Service/ Fluid Change

Got some info from the dealer regarding transfer case service. Depends on which manual you have, one of them is more specific:
32,000/ 24 mo- Inspect fluid level

64,000/ 48 mo- Change the transfer case fluid if using your vehicle for any of the following: police, taxi, fleet, or frequent trailer towing.

Re: DIY- 2011 Differential Service/ Fluid Change

All,

I have a 2012 Summit V8 with the ELSD in the rear and wanted to report that Mobil 1 75w-90 LS Synthetic Gear Oil works fine in the diffs in this vehicle.

No additional limited slip additive (Jeep or otherwise) was required for the ELSD unit in the rear diff.

Yep, the "LS" denotes that it is for limited slip applications. It can be used up front as well.

Re: DIY- 2011 Differential Service/ Fluid Change

Tackling this project of the differentials and transfer case in the next week. I had read the the fluid was 75W135 with limited slip differential additive. Going with synthetic. On the transfer case I see that a Shell fluid is recommended instead of ATF+4. would using ATF+4 be bad for the transfer case on the 3.6L or just an extra cross?

I believe that the correct axle lube is 75w90.
For the transfer case, it will depand on which brand of fluid you go with. Make sure that it meets the Shell 3403 spec. Amsoil meets that, the ATF+4 and the Mercedes requirements that are called out by Mopar for the T case.
