YJ DIY Posi Lock Writeup

I have been looking at everybody's home brew posi lock setups and thought I'd do it someday. Well, as luck would have it, my vacuum motor quit last week. No better time then the present. I used the NAPA locking cable that I've seen in other writeups, but didn't want to drill a hole in the housing as my jeep sees considerable time in the river in the summer. I decided to put the cable and attachment to the fork on the outside. I disassembled the vacuum motor and cut the diaphram and metal plates off of the shift fork rod. I welded a bracket to the end of the rod to attach the cable to.

I built a bracket that attaches to the top two mounting bolts of the housing. I drilled holes and used small cable clamps to attach the cable sleeve to.

I couldn't find a place in or under the dash that I liked, so I mounted the cable in the floor next to my t-case shifter.

Finished product. I'm happy with the way it turned out. It shifts in and out very easily and the 4x4 light in the dash still works also. I also like that i now have the option of 2 Low. Shouldn't have to worry about water entry from adding any more holes, and the shift fork rail has an o-ring on it. If this setup should fail for some reason, it could easily be shifted in or out and held with a zip-tie since its all external.
