I have an 05 rubicon . We were out wheeling and I twisted off the rear pinion and twisted the rear splines on the drivers axle. I got oem gear set, axle and set up kit. I pulled the axle from under the jeep and had a repuatable shop set up the rear . I brought the axle home installed it and now the factory lockers are locked according to the inst cluster. Both front and rear. Any guesses to why? Now keep in mind I only messed w/ the rear.
As a side note I did drive in front wheel over 150 miles to get home. After I pulled the drive shaft and the pinion out and shoved a rag in the empty hole.

I am assuming you mean they arn't working. Is so check fuse 24 and 25. 24 controls relays and 25 controls switches. If this doesn't help let me know.
