The posi-lok is around $200. You can remove the 4wd vacuum lines, and plug the ports on the transfer case.

I did something similar to be able to manually operate the disconnect, since I welded my front diff into a Lincoln Locker. Installed a manual vacuum switch,about $20 and 1/2 hour later I can disconnect the pass. side axle when in 4wd. Incredible traction, and can still 3-wheel for easier tight trail turns.

I'm comfortable with keeping the vacuum system, not too hard to work on and troubleshoot.[addsig]

	Transfer Case Mounted behind and driven by the vehicle transmission, the transfer case transmits power to the front and rear driveshafts in 4WD Jeep vehicles and offers high and low range.

	Locking Differential Provides even more traction than a limited-slip differential by “locking” the axle shafts together when the driver wants to do it. Locking differentials do not allow for wheel-speed differences and must not be used on dry, paved roads.
