Changing trans case, Front and rear diff fluids

Hey guys,
Im about to hit 40K and I wanna change the fluid in my transfercase, Front diff and rear diff. I have a 5.7L with QD2, so that means I have the ELSD in the rear, right? I was hoping to use,

Redline synthetic 75w85 GL5 in both the front and rear. On redlines site, it says that it doesn't require any additional friction modifiers. My question is, is that true or will I need to add a friction modifier in the rear? and because this fluid had a modifier in it, will it be ok to use in the front?

I only ask this because on their site it says "for most LSDs, no additional friction modifiers are required"

Red Line Synthetic Oil - Gear Oil for Differentials - 75W85 GL-5 Gear Oil

For the transfercase I suppose any ATF+4 that meet the 9602 spec will work?

Thanks for your help in advance.

Thank you, I actually read this which answered my transfercase questions. But my original questions still remains, Do I need to add an additional frictional modifier even though redlines site says it has it. because they also says "for most LSDs, no additional friction modifiers are required"


and will I be able to use that fluid in front even though it has the modifier in it?

Typically you do not need to add FM to Amsoil. Not in the Eaton EGerodisc unit anyway. I can not speak to Redline specifically but probably not with it either.
Yes, you can use the same (LSD compatible) oil in both units. The FM additive only affects the clutch pack operation and has not affect on the gears themselves.

Edit- the rear ELSD unit in the Jeep is the Eaton unit.
