How reliable is the AWD on a 2006 GC?

Hey all,

I am considering buying a 2006 GC with full time 4wd and a 4.7 engine. The car has 130,000 miles on it and seems to be in pretty good shape for it's age and mileage. I would be purchasing from a dealership that got it from an auto auction. I drove it over to a mechanic today to have him check it out, He pronounced it to be in pretty good shape. Pointed out a few minor discrepancies such as rear shocks leaking, needs new tires on the front. I got a look under the car, and the 4 wheel drive system seems pretty complicated. How reliable are these systems? What kinds of things go wrong with them? If something fails is it more likely to leave me sitting on the side of the road waiting for a tow than a 2wd GC?

Thanks,

Tim

They are really reliable and good systems. Which system is it? Quadra-drive or quadra-trac? How much offroading if any will you be doing? Being an AWD will leave your MPG's a little lower than a 2WD though.

I am not sure which system it is. There is not a owners manual with the car. It does have a Low 4WD that you get by stopping the car, pulling up on a little T bar located southeast of the shifter. I will do very little off roading. We live in the country and occasionally when it rains hard the roads can get slippery, but so far it has not been a problem with my 05 GC 2wd (Tboned & totaled by last Sunday).

There should be a badge underneath the shifter that states which system.

Still reliable either way... But there is a difference, and you should know what you have. Look under the shifter on the shifter bezel, and just for confirmation, count the bolts on the rear diff cover

I would say that the quadra trac at 130,000 miles will be more reliable. Simple open diffs instead of lockers. Especially if the maintenance was sub par.
