Try this with your Quadradrive
 
Now that it's colder out I want to see if you guys will participate in a little experiment with me. Now this is just for the guys with the 247 T-case and Quadradrive. Don't know if any Quadratrac owners are experiencing this or not but you can try it if you want. Anyway put your Jeep in the grass or some other low traction situation of your choice :D and leave it sit over night.Place a big piece of wood (log,4x4,etc)tight behind both front tires and in the morning put it in reverse and see if you can back over them in 4 All Time NOT 4 Low. Mine will sit there and spin the back tires till I stop. 4 Low will walk right up over the obstacle. 4 All Time in forward works fine cold. From what I gather on the good ole interwebthingy is that some people are having a progressive coupler loss of prime issue that seems to affect reverse when cold. Once it's warmed up everything's fine. I had it to the dealer last year for this when I got stuck 3 times backing out of my garage into deep snow. Front wheels were still on the dry floor and no power going to them. Had to put it in 4Low to get power to the front wheels. They rebuilt the front Variloc which imo had nothing to do with the problem but I'm sure some of you guys have been down that road before. Well I tried this test a week ago and still the same problem. Oh well back to fight with the dealer before my 7/70 runs out:lol: Just thought you guys might want to know about this so ya don't get embarrassed next to a Kia or something. Oh and before anybody says it I'm just too fawkin lazy to turn around and back into the garage:lol::lol::lol:

My WJ has Quadra Trac II, but is behaving the same. Had it parked once on an unpaved place with the nose a bit down. After some rain, the ground became slippery and in reverse the front wheels where not driven and the rear just spinning. Donīt know if this is a problem or just normal behaviour. In 4-LO the front wheels are directly driven, without the use of the progressive coupler.
But the problem is with the T-case and has nothing to do with front nor rear axles. So this experiment can be for Quadra Drive as well Quadra Trac II.

You sure you have the right fluid in the TC? If not, swap it out for Mopar only NV247 fluid.

If the dealer rebuilt the front varilok because of this, take it to another dealer. If they can't get the basics right I wouldn't trust them. The problem is in the TC, not diffs - like Frango said.

I backed out COLD over a mountain of snow last year, no issues. But then again, I change the TC fluid out every 12k.

Yep TC fluid changed with whatever the crap mopar calls for twice in 60,000 mi at $100 a pop:lol:

They actually did find metal in the varilock so there was an issue but still unrelated to this.I had them look at the front end cause of a pinion seal leak witch is pretty much SOP for a Dana WJ.

Since Mopar doesnīt make any oil themselves, they buy it from Mobil, fluid type 424, and give it their P/N and some extra $$$$ :D

Maybe I'm wrong or maybe it's different w/ a Quadradrive TC (I have Selec Trac), but I thought the TC fluid was just regular tranny fluid? :confused:

Re: Try this with your Quadradrive
 
The 5-45 RFE transmission uses ATF+4 fluid. The NV247 T-case uses "special" fluid, Mopar P/N 05016796 (which is in fact Mobil 424).
The NV247 T-case is used on Quadra-Trac and Quadra Drive jeeps.
Not sure which T-case is used on Selec-Trac, but it is probably the NV242, which indeed uses the ATF+4 fluid

I just change mine the other night. Tc fluid that is. Cost me $27.

It was due when it was in for the front end and they were whining about it being due.So in the interest of my warranty I let them do it.$100 t case flush and refill. That's why I usually do my own work but really if they actually flush it that's not too bad.

Re: Try this with your Quadradrive
 
I am experiencing the same problem with my '04 wj (WG) diesel overland, 'progressive coupler loss of prime issue' and when backing out of a garage up a combination of slopeing grass and tarmac, the rear wheels spin and no power is going to the front wheels. :confused:

Just checking to see is anybody has a know fix for this problem as my problem persists.

Just to go to shop and get a new progressive coupler installed in NV247 and change fluids regular?

Thanks in advance.
