Every automatice in 78/79 was a quadratrac. I don't know how many, but many of the 73-79 Wagoneers also had quadratrac.

Howdy, WM,

I'm new to the jeep scene. On my 76 CJ w/ quadratrack I've got a switch on the dash to the left of the steering wheel. The guy I bought the jeep from said that if I turn the switch to the right it will lock up the front and back axles to turn at a one to one ratio.
Do you know what this is called so I can research it and learn about it?
Thanks ahead of time for (if) answering my (probably) dumb question

Thats Quadratrac.

basically, it locks the wheels into 1.1 wheel ratio.

My 79 CJ is permanent 4 wheel, but in the sticky stuff, occasionally the wheels spin, thats when the quadratrac coms in, turn in on, get out of sticky stuff, turn it off.

Quadratrac si a great tool, but YOU MUST only use it when you wheels are slipping, it can damge the gearbox if you use it in normal driving, use it only when traction is being lost at the wheels.

Full time fourwheel drive systems use a diff in the transfercase between the front and rear driveline. The downfall of this system is that if ANY tire losses traction, all the torque will go to that tire, leaving the other three just sitting there. The Q trac uses a LS diff to help elimenate this problem, however there is still some torque loss. The switch you refer to locks that diff(and the two drivelines).

Thanks Jeepdaddy,

I understand the deal now. Kinda weird that they even built these rigs this way.
