I believe that the transfer case is the MP3023 used in GM trucks like the Suburban. The WK uses the NV245 and NV140.
If the MP3023 didn't have any problems with the heavier Suburban (Silverado and Escalade also IIRC), it should be OK for the WK2.

Yep, here is more info on the case for those interested.

Scott...explain to me how street tires add to the likelihood that a steering rack or 4WD system would fail?
I still love the Jeep, it is great on-road but in my case, I think I just got a bad one. I spoke to many guys here that had the new WK2 in the same desert for up to a week. No problems, just my bad luck.
But don’t tell me I am abusing the car. If you know anything about 4x4 wheeling in sand you would not keep hammering on the tire issue.
The 4WD system was fine after being towed the 4 or 5 miles out of the sand. Everything worked fine again, but it is still in the shop as it DID fail and it left me stranded in the desert. Fortunately it is winter here. I would have serious problems if this happened during summer. Anyway, it must be electronic and not mechanical as the problem sort of fixed itself. Reliability is becoming the big issue here. I bought a Jeep because I travel 100 miles to and from work every day, but I also needed a vehicle that can take me into the desert once a week or so.
I am still waiting to hear from Jeep, but I can promise you that it will be back in the desert within another week (but not without having a 4x4 recovery team on stand-by).
Jeep service has been outstanding! Probably the only reason I am not too pissed off, but I do need a reliable 4x4 that will get me in and out of the desert safely. All joking about buying a Toyota aside, I still believe the WK2 is the right vehicle for me. They just need to sort this particular one out.

Re: 2nd Breakdown in just over 2 weeks!!!

IMO...it puts undue stress on the drivetrain and its componets. Its constantly fighting for traction. I wouldnt take Super Swamper mud tires to the track and race the 1/4 mile.......and I wouldnt take street tires to play in the mud or sand. I am just going by your pics and the fact you seem very adventurous. Its my opinion you need some proper tires....nothing else.

Re: 2nd Breakdown in just over 2 weeks!!!

I agree that sand, NOT A/T tires would be better, but that is not the reason it failed.
BTW, any idea what a desert tire looks like?

Re: 2nd Breakdown in just over 2 weeks!!!

if it is working again after being towed out....then it is not broken. It sounds like the system is being overwhelmed for some reason. Your guess is as good as mine on that one.

Re: 2nd Breakdown in just over 2 weeks!!!

Agreed. That was exactly the feeling I got. Almost like the Jeep was trying to say "hang on a moment, give me a break!"
I am very curious as to what the Service guys will say. Should hear in a few hours.

Re: 2nd Breakdown in just over 2 weeks!!!

I think you need to start using Low Range and see how it goes?

It's piss weak to have to do that (promise you wouldn't need to in a Nissan or Toyota!), but I think something might be overheating (likely the centre diff clutch pack) and having a freak out. Low range locks it, so no slippage therefore no heat.

Re: 2nd Breakdown in just over 2 weeks!!!

Good point with the low range, but I want to make sure it does not fail again in normal HR mode. No compromises.
BTW Marlin, I did test it in first and second gear and it is slightly better than in drive. You donít loose traction at a critical moment as you would in Drive when it changes up/down.
Also took the tire pressure down to 22 psi and then 16 psi. Both are better than the normal 36, but 16 works best and no problems.
The 4WD SYS failed before I could test Low range. It just would not engage. Next time.

Desert tires look very similar to wheel barrow tires.




Hope they sort it out for you quick!
