I found all this info earlier but cant find it now. I got 40k miles on it right now and want to change out all of the fluids before winter. I got all of the capacities but just wondering what type of fluid to use in front and rear end.

For your front and rear diffs, you will want to use 75W-90 Gear Lube. There are hundreds of threads about what brand is best. I use all the fluids from AMSOIL. AMSOILs Severe Gear 75W-90 is one of the best on the market today. It is a full synthetic fluid that has a 100k mile drain interval. If I can help with product information or pricing, please let me know.

Take care,
