Hello, My 4 wheel drive is working, the problem is the front end is not disengaging. The actuater is getting vacume all the time. If I pull the vacume line off of it the front end unlocks. The transfer case is not overfull of oil so this leaves me to suspect the vacume switch on the transfer case. How does this switch work and does it just screw ouy to replace? Thanks, John.

Hello, Picked up a new vacume switch at the dealer for $65.00. Works like it is suppose to now. The ball in the old switch was siezed. John.
