Good afternoon everyone and Happy Friday!
I need a little help to straighten me out a bit.
I have a 2004 WJ, i6, no tow package, Quadra-Trac II Transfer case, 42RE transmission, D30 front & D35 rear with 170+K miles.
I've only had this vehicle for about 3 months and am finally seeing some time opening up to actually do a full maintenance/tune up. I've been slowly getting parts to replace some things just because I don't really know the history of this vehicle (maintenance wise) and I think I've purchase some stuff that I don't really need and might need to return/replace for the correct stuff.
1. Differential. I've searched for a while but still kind of confused about the Veri-lok. As mentioned, I have the Q-T II and from my understanding is that only the Quadra-Drive has the Vari-Lok system. The only Q-T II that has it are those with the tow package and only on the rear diff. Is this correct? If so, I have to return the front shafts that I ordered and F.M. back and get new shafts for none-VariLok front shaft.
2. When I replace the front axle shafts, I want to replace all the diff fluid as well. I was looking into the LubeLocker diff gasket and from what I find is that the D30 front can use it. A lot of people mention that for the rear just use RTV but I also see LubeLockers for the D35 rear.
I would like to get both front and rear LubeLockers but I don't know if I can use the one for the rear. I'm 90% sure I can use the one for the rear since my WJ doesn't have a VariLok system?
3. If my WJ doesn't have Vari-Lok, I can use the 75w140 RP gear oil without FM, correct?
Please advice. I would like to place my orders in by today so that all I need will be here for next weekend.
Thank you very much in advance,
