Jeep YJ Center Axle Disconnect (CAD) Delete/Bypass

The Jurassic Jeep failed to engage four wheel drive at the Maple Syrup Festival yesterday. I assumed it was the vacuum-driven center axle disconnect system failing to engage the locking collar. I decided to bypass the vacuum motor and keep the front axle's locking collar engaged full time. This still leaves an open front differential, but the front drive shaft will free spin with the wheels when the transfer case is in two wheel drive. Shifting the t-case to 4H or 4L will immediately engage four wheel drive. No waiting for vacuum and hoping for no leaks... or getting stuck in two inches of mud on flat ground in front of your friends...
