Drive Train Axles Bearings problem
1988 Chevy Truck V8 Four Wheel Drive Automatic 173, 43 miles

I can not figure out why my front drive unit will not engage. When I pull my 4 wheel drive shifter in place my transfercase shifts in, but my front drive does not. My front driveshaft turns as does the rear, I am at a loss?

Do you
have the same problem?

No

Check te vacuum modulator on the axle for vacuum. Chances are you have a vacuum leak.
