It would be the 229 in the select trac setup. Vacuum problems are common if the system has not been gone over. First thing to check is if the vacuum motor on the xfer case is bound. Try switching into 4wh while someone trys to move the vacuum motor by hand. Make sure to set the emergency brake and block the wheels. Alot of times the linkage/vacuum motor is frozen from lack of use.
