Hit 60,000 miles a few weeks ago so I did some maintenance. Oil, trans, transfer case, front and rear diff and brake fluids. The fluids were just over $300 and I did it myself in about 3.5 hours. Just bought new tires also- Michelin Defender LTX in the OEM 275/65/20 size.

Used these fluids:
Oil: M-1 5W30 EP (7.5 qts)
Trans: Motorcraft Mercon LV (8 qts for drain/fill)
Xfer Case: M-1 Synthetic ATF (2.5 qts)
Rear Diff: Valvoline 75W140 (3.5 qts)
Front Diff: M-1 75W90 (2.5 qts)
Brakes: DOT 3 (2 qts)

+1 tube of RTV for the rear diff.
FL-820S filter



Fluids...Yep, I used 5W30. Flame on.




Rear diff...looked very clean.

 

Nice. Always feels good to have fresh fluids. I switched my '11 to 5-30 1k ago........and it hasn't blown up yet!

 

Can I ask why you used Mobil 1 fluids on the front diff & T-case but Valvoline on the rear diff and then Motorcraft ATF in the trans?
I'm also planning to use 5w30 engine oil for future changes.

 

That looks really nice. Grease is cheaper than steel.

 

Thank you for posting this! I am about to do the same maintenance. You did not feel the need to change trans filter?

 

Trans fluid: Nothing and I mean nothing aftermarket I could find is licensed Mercon LV. I just went with the Motorcraft ATF...the fluid is only $6.xx per quart. Got it at O'Reilly's.

Bought Valvoline gear oil because that's what O'Reilly's had. They did not have M-1 in 75W140 and I wasn't going to look everywhere for it. That stuff is $22/qt
