I fixed a main vacuum hose that was off at the transfer case and hoped for 4 wheel drive but when I put it up on 4 jackstands in 2 wheel drive the driveshaft turns and so do the wheels but in 4 wheel hi and low the driveshaft spins without any problem or noise but the front wheels do not but spin freely by hand.
