Just checked out a 2001 Grand Cherokee that I really liked. But I haven’t done too much research on the quadra-trac system yet. Is it reliable? Any common problems? Doesn’t seem like there’s much of a difference in mpgs between this and the regular system in just RWD mode. It only had 78k on it if that helps. Any info is helpful. ---

Paulo the AWD jeeps have HORRIBLE fuel mileage. I think a 4.0 RWD will get you maybe 16/17mpg while the AWD 4.0 I’ve heard get ~14mpg. If this jeep has the V8 good luck lol, hope you don’t have a long commute. ---

What drive modes does the quadra-trac have? My 2002 Grand Cherokee has the Quadra-Drive system and has just 4HI and 4LO, with no option for 2WD. If it’s anything like that, it uses a viscous coupler to determine power between the front and rear axles. It’s a great transfer case but after time this will wear out and need replacement. Mine has 75k and still works like a charm though. Fluid was always replaced on schedule which I’m sure helps. I’ve heard that the replacement cost is around $300. I think I will swap in a NV242 Selec-Trac when my coupler wears out. Supposedly it’s pretty easy. ---

I think I will swap in a NV242 Selec-Trac when my coupler wears out. Supposedly it’s pretty easy. The prior version used the viscous fluid coupler; the ones in the 99-04’s used pressure from the transmission pump instead, they don’t wear out and break like the older VC ones. The Quadra-Drive is the best one of them. I’ve got an '04 GC Limited with the Quadra-Trac II system. The difference is that the Quadra-Drive has the sensing differentials similar to what the Transfer-case does; the Quadra-Trac doesn’t have the diffs. The only weakness that I see/have read about is the lack of lockers/limited slip in the front and rear axles. It was an option in the rear-axle, but the front is an open-diff if you don’t have the Q-D system. I’ve got the 4.7L V8, and get 15mpg normal driving, 20 on the highway. I’ve had zero issues with the 4wd system. I suggest doing some reading at [http://www.jeepforum.com/](http://www.jeepforum.com/) they have TONS of info over there on these jeeps. ---

Don’t worry, it’s a Jeep thing. Might as well buy a Blazer if you’re gonna get that mpg, I say Toyota Tacoma so you can move stuff and tow bikes :tup: ---

Good info guys, thanks. Chris, it has a tow package, no worries. 😉 ---

Hi retards, I see nothing about gas mileage. I think the 249 is the quadra trak. Anything in the WJ I hear is pretty good. ---

Keep in mind that I have an all highway commute to work, and it’s not very far. I wasn’t incredibly concerned with gas mileage, just curious if the quadra trac was much different than just 2WD. But it seems like it’s only 1-2 mpg different. No biggie there. I was mostly concerned with the reliability of the system over the traditional part time 4x4.
