<strong>Uhh...correct me if I'm wrong, but the qtrac used locking hubs, at least mine does. Also, I have a lever to engage the qtrac, it's not always running in 4wd. I think a lot of disdain for the quadratrac stems from a lack of understanding of the system. It's a perfectly good system, and actually it still exists today, but replacement parts are hard to find. Now I know that there are companies out there making full time conversion kits for the qtrac, which would engage the driveline components, up to the locking hubs, full time, but that's only a last resort. Due to the lack of understanding of this perfectly fine T/C, you can usually pick up the qtrac fairly cheap. Don't let the driveline stop you from buying this thing. Good luck.</strong></font><hr /></blockquote><font size="2" face="Verdana, Arial">You could be right, but to the best of my knowledge Quadratrac never had a TC shifter that disengaged the front drive (from the factory)only a high/low range shifter on some. I had one with, and another one, that was behind the 304 v8 that did not have any shifter, full time high range only.
They had a one piece metal plate that engaged the front wheels "full time"instead of hubs.( a good part to have on board incase you grenade a hub!) Installing lock out hubs is as easy as on any other jeep, they just bolt on more or less but the front driveshaft still turns as you can not disengage the tc( unless it has been up graded with a kit)
The transfer case is chain driven, That chain eventually stretches and jumps the teeth on the cogs. i dont recall whether or not there is an adjustment to take up the slack but once it loosens up you're hard pressed to limp it home on the road never mind getting it out of the woods!
I took the front driveshaft out when i was commuting to school to save on fuel(minimal saving i think) but if you do this you need to lock in the emergency drive in the glove box or you wont move!
That emergency drive is run on vacume, if there are any leaks in that system it wont work right, just another potential problem with the system.
If you have a good deal on a jeep go for it weather or not it has quadra trac! there are so many jeep parts around that they can easily be changed!
I rebuilt mine from the ground up, it used to have the Qudratrac system, i scrapped that and found a 82 CJ7 that i took the wide trac axles, TC and tranny out of and bolted it into mine.
Bottom line, if it is in good shape and everything works, its a good deal? buy it and worry about up grading it later if it needs to be, just drive it and have fun!
