Same problem 3 times in 4 years on my Junk out of the box, more wheel bearings & ball joints than I can count, 2 fuel pumps in five years, 99 ZR2. One time it turned out to be a pin hole in the vaccum line to the front diff acutator, then the other two times it was the actuator on the transfer case. If its the T-Case one, try taking the actuator off and follow the wires into it (under the plastic cover), They usually corrode where they're attached to the motor and somtimes are repairable. What the hell was wrong with front leaf springs and a shifter to put it in 4wd?
