\'94 yukon I just picked up a 94 Yukon, and got it stuck on the beach this morning. When I entered the beach, the 4WD was working, when I went to leave the front axles were dead, no light nothing. After some cursing, digging, and airing down I was able to sneak away from the tide line and get home. A shop I trust was willing to look at it right away, the drive shaft was turning but not the wheels. Well it turned out to be an "actuator" in the trans axle, but the funny thing is the dealer replacement part was a diffrent design with an adapter harness. The parts guy said it was due to a faulty design in the first place. Anyone else have a problem like this?
