To answer your question accurately, more details are needed. Two things have to occur when you activate the 4x4 system: the transfer case engages the internal locking hub, which turns the front driveshaft; the second is the 4x4 hubs being engaged to rotate the front wheels. The first thing to be done is to determine if the front driveshaft is turning. To do this, have a partner squat down near the driver’s side of the vehicle and observe if the front driveshaft is rotating when slowly driving in 4x4. If so, then the concern may be in the front hubs; if no rotation is noted, the concern lies in the transfer case. There are two different types of front hubs: manual- where we have to get our shoes muddy to activate them or automatic, which lock when the driveshaft is rotated. I hope this helps.
