Maybe a moderator can move the thread over to the right section.

no. 4wd is controlled by your t-case and only your t-case. this mod simply takes the 2-piece shaft and makes it essentially a 1-piece shaft. Jeep did away with the silly CAD design in the early 90s and all Jeeps since have come with a 1-piece shaft.

the only downfall is that if your front driveshaft ujoints are bad, they will vibrate at speed. not really a downfall though, since if they need to be replaced, you should replace them.

Or you could replace the passenger side axle shaft with a 1 piece Cherokee axle shaft and fabricate a cover to eliminate the cad vacuum fork.
