Fluid Recommendations

[brian42]

I’m sure that there have been plenty of posts on this but I can’t find an answer for all of my questions so I’ll just ask one big one.

I just bought my toy last fall. I’ve been meaning to change all my fluids so that I know what I’m running but haven’t gotten around to it. After this last weekend in the desert I think it’s about time.

What is everybody’s recommendation for fluids and filters? I’m talking the whole shebang. Engine, Tranny (4R100), differentials (Dana 60 up front and Sterling 10.50 with limited slip in back), transfer case, cooling, power steering and brake. Even the windshield washer fluid if you feel like it.

Currently I’m running Rotella T Synthetic 5/40 in the engine with a Motorcraft filter. I also have a Motorcraft fuel filter too. I also recently flushed my cooling system, replaced the hoses and filled it with Zerex G-05 Gold (50/50 with distilled water of course) and put in the billet thermostat housing and 203F thermostat while I was in there.

Please feel free to also mention anything to avoid as well.

Keep in mind that my ’03 has 156,000 miles and I’m still on the original build of the tranny (knock on wood).

The motor oil you are running is good stuff but many here are using AMSOIL or ROYAL PURPLE in everything. Me personally I use Rotella in the motor and run AMSOIL SYNTHETIC in the tranny, frt/rear diff, and transfer case.
