I had the shop replace the original electronic hubs with warn manuals. I tried it this morning, and 4x4 only worked when I engaged the knob on the dash. It also completely dis-engaged when I switched the knob back to 2wd. The hubs were manually put in the lock position twice.
I thought the vacuum engagement would no longer work? Manuals are in or out manually only correct?

When you turn the knob to 4x4 the transfer case will engage then it will also activate the vacuum for the hubs. the truck will kick to a lower gear with transfer case engaged but the hubs are not. thats where the manual hubs come in you will have to lock them in order to spin the wheel.
THE KNOB ON THE DASH ENGAGES THE TRANSFER CASE, WHICH TURN THE AXLES. THE MANUAL HUBS LOCK THE WHEELS TO THE AXLES.
