I recently purchased a 1977 CJ7 with Quadratrac and manually locking "Sears" hubs. Does anyone know if the Quadratrac is compatible with these hubs. I have been told that these Jeeps should not have manually locking hubs. I also cannot find the catalog that these hubs came from. I have found small exerps from an old Sears Jeep catalog but nothing telling me what I need to know.

I've never heard anything about not being able to use locking hubs with the warn quadratrac. I you want some goods ones get Warn. Mine are great.

The quadratrack unit is a full time 4x4 unit that uses a limited slip dif carrier in the transfer case.You cannot use locking hubs with the stock system as the diff will allow torque to the front axle which is unlocked. Milemarker makes (made?) an aftermarket part time kit that converts the diff to a part time unit. My guess is that somebody has installed one in your jeep. With the transfer case in the "unlocked " position, (the selector should be on the glove box) lock both hubs in and jack one tire up. If the tire/front driveline spins then you have a part time kit.

That is assuming that the front axle diff isn't a limited slip!!!

You don't need hubs on the quadratrac, it's fulltime 4wd. If you unlock the hubs your Jeep won't move. Just lock em in and go. It won't hurt any thing.
