Out: no idea, looks like it was changed at least once (had some blue gasket maker on it, most say OEM is grey)
In: Lucas 75w-140 synthetic with Motorcraft XL-3 Friction Modifier.
I have heard a lot of bad about Lucas gear oil (mainly due to the Amsoil whitepaper on gear lube, but that was several years old and a different oil weight). So far no issues, rear end chatter has stopped, so I am really not worried about it.

Suburban 1500 Z71 -03 203192Km Front Diff
Out: No idea but some real black mess
In: Mobilube 1 SHC 75w90
Feels like a donkey when i didnt check the diff fluids before. A full serviced vehicle will had all fluids changed in my opinion but in this car it not looks like its been changed.
Will do the rear diff and transfercase too when back home in Sweden after this roadtrip.

^ Not a super unusual experience. And I'm not too surprised that a t-case is readily available in Moscow. Too bad you had to deal with it though.
My latest change...
Out: Royal Purple MaxGear 70W90 with about 80K miles on it
In: Valvoline SynPower 70W90.

Out: Unknown, looked quite cleaned for never touching it.
Front was pretty bad so im assuming the rear was done at some point.
In: Mobil 1 75w-140 rear and 80w90 front.
Did the transfer case also, came out very nice and red, never touched that so it porbably had 200k on it.

8.8" 3.90 motive gears auburn pro differential
4 qts torco rgo 80-90 going from quaker state 80-90
auburn recommended a dino oil 80-90 gear oil so thats what i have run. the rgo is a bit quieter and from what i can tell runs cooler.
for my towing rig i would like to try the sgo synthetic.

The Torco RGO/SGO gear oils are some really good stuff (I've used them both in the past).

98 MGM 143K
OUT: Very likely stock
IN: Valvoline White bottle High performance 80W-90. Had Lucas but this site convinced me to exchange it.
Had a small leak into the parking brake, ended up changing all seals(M/C) and bearings(Timken). With some comparison shopping the bill was under $50 with the Permatex fancy rear end gasket maker.

Is that a clutch pack type diff in the 5th gens, or did they make a Torsen type for that IRS pumpkin??

Durango Front diff (105k miles):
out: Cover off, chocolate milk drained, cleaned with brake cleaner.
in: SuperTech semi-synthetic 75W90, 1/2" below fill hole.
Durango Rear Diff: (108k miles)
plan to replace open diff with Spartan locker.
Not sure if I should use 75W90 or 80W140.
Truck is AWD and never used for towing. leaning toward 75W90 ST like the front.
