Try checking the vacuum lines on the axle.
when i try to engage the wheel wheel drive it grinds i have my truck in neutral what could be the problem what am i doing wrong
on almost any automatic 4 wheel drive the gears that engage the hub could be stripped out or stuck cause if you know what the gears that engage the wheel than you would know that they are fradgile lookin but that is what im thinkin it is cause that's what happened to my truck so you probally need some manual hubs to make sure they always work or the problem might be that your transmissoin to the front wheels might be jacked up I don't know Fords that well, but many 4 wheel drive use a small motor basically to engage the 4 wheel drive. These can go bad or become stuck. If you engage the 4 wheel drive with a switch, it is this type. Could be the motor, the switch, fuse.
could be the 4 wheel drive module located behind the glove compartment. If you don"t hear a click when you press the button to engage the module isn't working.
No!
only if you disconnect both drive shafts.

Check vacuum lines and intake gasket for leaks. Replace fuel filter and check fuel pressure. Give it a thorough tune-up and have an exhaust shop check the pressure before and after the catalytic convertor. There are several things that could cause it to stall...
It could be the shift motor on the T Case. Or it could be the automatic shift button switch on the dash.
Most four-wheel-drive vehicles are controlled by the transfer case. The transfer case has many years in it. A bad year in the transfer case will cause the vehicle not to engage.
may need new transfer case or transfer case controller
check your timing & up your idle a little
