All wheel drive problem

I have a 2000 JGC Limited with quadratrack II and every time I make a hard turn, like pulling into a parking space or making a uturn, the truck seems to bounce. It feels like the U joints are fighting each other. Is this normal?

The viscous coupler is gone. Are you still under warranty?

No warranty unless this considered part of the drive tran (70,000, 7 years). Is this expensive, can any shop do it, can I do it?

If you don't know what a viscous coupler is, I wouldn't mess with it. Hell, I DO know what a viscous coupler is, and I wouldn't even mess with it. It is part of the drivetrain however you will want to make sure that it is covered before you sign your vehicle away.

It was my impression that, unlike the original Quadratrack, the Quadratrack 2 system doesn't use a VC in the transfercase. Correct me if I'm wrong.

Here is a link to jeep's site that explains the various 4WD systems. In the Quadratrac 2 system it makes mention of a clutch pack being used to transfer power from the rear to the from wheels, not a Viscous Coupler or VC.

Here is what I found out today.

My 2000 JGC Limited with the Quadratrac II has a NP 247J transfer case. It does not have a Viscous Coupler instead it has something called a "Pump Transfer Case" Mopar#5012329AA in the transfer case. The cost for this part is $875. I did a lot of investigation on the web, talked to the dealer and several Transmission stores and found out that a lot of factors can affect this situation. One big factor is the condition of the tires, things like uneven pressure, uneven ware or different sizes on the same vehicle will confuse the all wheel drive computer and make it think the wheels are slipping and put it into FWD. I also heard from two people that changing the oil with fresh oil could solve the problem.

So since the tiers on my Jeep are bad I am going to replace them and replace the oil in the transfer case. If I still have the problem I will more than likely replace the transfer case since I can buy a guaranteed rebuilt one for $800.

Any thought?

Thankyou,

I see you have a new Toureg GCLifer. How do you like it? Have you tested the 4WD on it yet? I know this isn't a VW forum, but I think we'd all like to know, since it is a new kid on the SUV block.

Okay, okay, now I was walking on eggshells by even inquiring about another SUV on this board, but to say that the Toureg is your vehicle of choice qualifies as a sin around here.

yeah, that's the nature of FWD. If you make a very tight turn, all the way locked, you're going to feel what you are feeling.

Heres what I did, I changed the oil in the transfer case, put four new tires on (Michilen's) replace two out of round rims and the truck runs great. No more jumping or binding when I turn it tight and it just seems to run better. I thing the out of round rims were making the transfer case think a wheel was slipping and it was putting it into four wheel.

That great! I'm glad it worked out for you, and didn't cost you a new T-Case.
