just to throw this out there.. but if you off road a lot like i do, then buying a good quality oil for the diffs isn't practical as it is *usually* emptied out after every trip and replaced.. i just buy w/e is cheapest and thickest and am on my way.. but if you don't then yes on the Mobil 1.. and it never hurts to throw in an additive even if you don't have limited slip... it quiets any chatter down you may have..

 

I use this http://www.royalpurple.com/gear-oil.html and It's amazing. I could tell a difference the first day I put it in, and I haven't went back.

 

What is the maintenance interval for the diff's and t-case, and tranny for that matter? What rears and t-case are in the 04 WJ's?

Thanks for the info. What fluid can be used in the tcase besides the Mopar fluid?

 

I belave you should only use the NV247 fluid from the dealer. Im not sure if there is something out there that you can sub in. I would just buy a few quarts and do a flush. Good luck
