Emergency help please

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?

This worked one time on my front Rubi locker-

Jackup one side so you can jossle the tire (you know twist)-at the same time have the driver cycle the elocker switch and pull out of 4lo--

If that doesn't work, anotherwords, if the tire you have in the air will still stay "locked", then put it in 2hi and driveit home --that'll get you off the trail-

Stay at or below 20 mph and even though it's not the front---take it easy on turns--there's a chance that because of the speed it'll try to "kickout" of elock-

Good luck

JIMBO

If it happens again, pull the fill plug, and with a common screwdriver pry the locker plate (disc) to the right.

It'll depend on the dealer and any mods your buddy made to the Rubi--

Tell him good luck

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?

Anti-spin will power both wheels but has a limit. One wheel will eventually spin.

A locker will lock both wheels together and not allow one wheel to spin at all.

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...

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.

I should hope so...if a locking diff isn't intended to be used on a trail I don't know why it'd come stock on a Rubicon
