fluid changes

[builderpaul]

Hi,

going to change my rear diff/front diff/transfer case fluids. Truck in signature.

 

Question 1:

Owners manual has a 75-90 synthetic (#12378261) in the rear and an 80-90 axle lube (#1052271) for the front. Can I just use the synthetic on both?

 

2:

Owners manual lists a manual transfer case and says use dexron-lll. It also lists an automatic transfer case and says to use auto-trak-ll. I have an automatic transmission with push button 4x4 is this a manual or automatic transfer case?

 

3:

Do you know the capacities for the rear diff, front diff, and transfer case? If so could you list them?

 

Thanks

On the axles, I used synthetic in both, but had to go with 2 different brands as Mobil 1 didn't have gear oil in one of the weights. So I stuck with the specs.

 

The transfer case you described should take the Autotrac II, or the "Blue Juice" as some of us call it.
