Extreme vibration and grinding in 2 wheel

Noises problem
1998 Mazda b4000 6 cyl Four Wheel Drive Automatic 112000 miles

We replaced the rear end because a mechanic looked at the truck and said the gears where worn. After we've fixed it, we took it for a test drive,and everythings was fine until we hit 70 mph, just like before, it started humming very loud like the axle was trying to stab. Once we engaged it in 4 wheel drive hi or lo, the noise goes away, and the vehicle opperation is normal. Can you help?
