Just got a call, need a CV Boot and a tie rod, so, since the car will be there overnight anyways, I have decided to let them do my next project as well... fluid changes.
Front diff
Rear diff
Transfer case
Manual Transmission
Power Steering

My plan for fluids is:
- Differentials (front and Rear)--Original fill was SAF-XO. This translates closely to a 75w-90 GL-5 Gear Oil.
- Transfer case--Original fill was MTF-LT1 P/N 83-22-9-408-942. Original was found to be very close in properties to a "MTL" GL-4 spec 75W-80 Gear oil **Note: The Bentley manual states, "recheck oil level again after driving car approximately 200 meters."
- Manual Transmission--Original fill was MTF-LT1 P/N 83-22-9-408-942. Most common replacement is D4 ATF, BUT, the "best/smoothest" result is said to be 2/3 D4 ATF and 1/3 MTL - that would be my 1st choice, if possible.

All that should make it a smoother ride than ever
