    I am thinking about doing this annually (along with the rear diff). It’s fun and not too expensive. Might even use the cheaper WalMart gear oil. I drive about 15k miles so my gears will always be in fresh oil.

    I would question their logic. I use Amsoil and have for some time. I know Amsoil runs cooler in differentials, I've seen guy change quick change rear ends right off the track with bare hands. One thing to note is Amsoil is the only true synthetic. Most are either mineral oil or some combo of pertro. With this mind Amsoil is slicker....and doesn't breakdown like most oils. You can get Amsoil test results from their site.

    Went to my local dealership last friday to get the necessary o rings for the frt & rear diff, as well as the o rings for the transfer case... The parts clerk stepped outside to have a look at my rear diff to see if it was limited slip... while kneeling down on the driver side, he pointed out that my diff was electronicaly activated ( there is a cylindrical motor) on the axle housing. Told him I planned on using royal purple with positive reviews from others on this site. He commented that no limited slip additive would be required.
    Just a fyi,

    Amsoil is Group V along with Redline and Motul. But, even these will use Group 3/4 add packs.

    Just changed my Rear Diff today for the first time. I'm at 53k and missed the first change. Rear diff oil wasn't really bad; still kind of light brown-ish. Soaking the Front Diff and T-case bolts tonight and will hit them tomorrow. I used Mobile 1 75w-90w GL 5 with LS already in it. Took a test drive and noticed how much smoother it is. Looking forward to doing the other two.

    Just did all 3 fluid changes today, and greased the drive shaft while I was under there. Front diff and t-case oils looked good and clear still, but the rear diff was pretty black and soupy. Now they’re all fresh and ready for winter.

    Fun Fact: a 15/16” socket will work perfectly if you don’t have a 24mm.

    Did my transfer case and rear end awhile ago, finally got around today to do the front differential, a little PB Blaster, and the plugs came right out, refilled with Amsoil Severe Gear 75w90, piece of cake, thanks to the pics from the original poster. Now it’s Miller time !!

    Edit: Just realized I’m posting in 2nd gen forum, but I think it’s probably just as relevant.


    I did mine today for first time at 45k. Front had a bunch of sludge and was really black. Rear and transfer case were just cloudy.

    This is the final mix.

    Did all three this weekend 185k. Bought all six plugs and gaskets new for $35 - northeast salt winters! So glad I did, both front diff plugs stripped and rear diff fill plug seized even after soaking with PB Blaster overnight. Used cold chisel and 5lb hammer on plug edges to turn and remove. Fluids all looked good with no metal on magnets. Refilled with Valvoline 75w90 conventional and Lube Gard LSD Additive in rear. Also hit all axle grease points while under. Thank You All for the posts, unbelievably helpful!

    I did my tranny, transfer case and both diffs last weekend with Redline MT90 and Redline 75W90. My truck only has 20,400 miles, but it’s Five years old. Everything went smooth. It might be my imagination, but the shift to second gear seems smoother.

    better suspension....
    First time doing this today - I managed to get about 0.9-1 quart of oil into the transfer case before the fresh oil was coming out of the fill hole. Anyone else had similar issues with the transfer case taking less oil than it's supposed to?
