Quadra trac-part time kit question

[116gtv]

G'day from Oz, my first post here..

I recently bought a 79 CJ7 AMC 258 i6 / 4.2l QuadraTrac . interestingly, it has free wheeling hubs, so I'm wondering if it had a part time conversion fitted..

Would it be correct that a QT front drive shaft won't spin freely ever, unless it had a 2wd conversion? Just tested mine when it was parked in gear, and the front shaft spins freely.

Want to change the fluid but dont know if quadratec fluid is a bad idea as automatic transmisions fluid is recommended for part time conversions...

thanks for your advice!

A QuadraTrac , as installed from the factory, will not work with open hubs up front.

If you were to install hubs and unlock them, you'd burn out the Limited slip clutches in about 2 minutes. You also wouldn't move more than a couple of inches. The only way to prevent that is to keep it in E-Drive (part time 4wd). I owned a 77 Cherokee that was set up like that. The previous owner had put in drive hubs and just left the E-Drive engaged all the time.

If the front driveshaft free spins with the hubs open and you can still get the Jeep to move when you put it in gear, there's certainly a part time kit installed.

In that case, adding QT specific fluid is not necessary. The additive is for the Limited slip. It won't hurt anything being in there but you don't need to specifically add it.

Thank you, I will replace Transfer Case fluid and see what comes out. Drives fine in 2WD so it must be a conversion. Really appreciate your response guys.. thanks again.
