<strong>Lee N,

Thank you, I will check out the vacuum solenoid, lines, and actuator for leaks and also check out the actuator. I don't have Active-Trac. It is doing what you described.</strong></font><hr /></blockquote><font size="2" face="Verdana, Tahoma, Arial, Helv, Helvetica, Sans">Actually, you do have Active-Trac. That is the ability to drive in 4 wheel drive on pavement as opposed to 4 hi lock. The Active-Trac (or SelecTrac in Australia) was installed in all Gen II's (1992-2000?) and allows shift on the fly. It uses a slip coupling on one front half shaft and a vacuum shift actuator to disconnect the front axle instead of using locking hubs on each wheel.
