I used Mobil 1 75W-90 in both front and ear, it's as easy as changing the oil. Here is a link to a how to write up

Did mine at 10k miles. Use 75W-140 in the rear if you tow. A bottle pump really helps, picture is attached:

I tried looking for those damn bottle pumps here in Canada- NAPA, Canadian Tire, Lordco and it was a no go and most never heard of them
. When I was down in the States last week I stopped at O'Reilly's and cleaned them out on the these bottle pumps (5 of them) guy was wondering what I was doing.

i need to pull mine to put some fresh fluid in (i'm almost at 50k and i've done a few wheeling trips lately) and to repaint my riddlers. i enjoy doing differential service. it's simple and i kinda think the gear oil has a nice smell to it. and the jeep is pretty simple even if you are going all the way and pulling the covers. i did the rear axle of a dodge sprinter (those big goofy looking work vans) the other day and while the bolts were easier to get to, i hated having to crawl all the way under the damn thing to get to the diff. with the jeep it's right there.. no army crawling under a big spare tire or anything like that. oh, and the bottle pumps are very handy. good for doing fluids on the trans and tcase too. definitely do the service yourself. don't let the dealer have all the fun

I declined and will buy the equiment to do it at home. Plus, the only thing that bothered me was resealing the covers and I see now that many fine vendors on this forum sell seals to use in lieu of the other. Plus, I might be out $50 on initial equipment: torque wrench, drip pan and oil...will save HUGE in the long run. Plus, there is a great write up on this forum...just search diff change and you can't go wrong!
