if its the vacuum actuator...buy a non-disco axel shaft and swap it in. and put a hard plate over where the actuator used to sit. Unless you feel like dropping $210 for a posi-lok

Zach is right probably the cheapest and easiest route

do a home made posi lock can do it for around 30 prolly

x2 get rid of the 2 peice axle shaft, they are crap.

That is a HUGE PITA, I tried it and it didn't work so I just dropped the dough for a posi-lok. I wish I had known and just swapped axel shafts out. would have been so much cheaper

That explains the two piece axle shafts....its called a Central Axel Disconnect

A posi-lok eliminates the vacuum actuator and replaces it with a manually operated cable system.

GO-BOLTS!

ok. so when you get rid of the cad garbage, which im doing(going to a non-disco with 4.88's and lockright) what do you do with all the vacuum/electrical wiring crap coming from the transfer case? any advice appreciated.
