On the trail, buddies rubicon, rear locker will not come unlocked. Tried pulling the M3 fuse, disconnected battery, drive it in reverse. Anyone have any idea what we can do on the trail to get it fixed?
I'm not trying to be a smartalek. Trying to educate myself. What does a rear locker do that an Anti Spin (as Jeep calls it) /Positrac rear end doesn't?
posi-trac is GMs brand of limited slip. Limited slip merely limits the slip speed between the two axles - one can still turn faster (thus apply more torque) than the other. Lockers do just as they describe - force both axles to turn equal speeds - thus apply equal torque...

The wagon should, of course, be as light as possible, but strength should not be sacrificed to lightness, for on any but the regularly traveled roads, the wagon will get many a hard knock...
If anyone is curious, the carrier bearing failed and caused it to stay in the locked position. No idea how but thats what the dealership is saying. The good thing is that TucsonChryslerJeep is doing the work under warranty.
