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.
