I have this 2000 Ford F-150, it is having trouble engaging the front diff so it can shift into 4x4 properly, if I shift into 4x4 at like 30 mph it grinds if I am moving very slow it doesn't. Its not the transfer case or the front diff, it is a vaccume problem. What are the things that go bad on these? Any advice

On this truck you can engage 4WD high at any speed up to 55 mph. (4 Low is only in neutral)
By the sound of it, the shifter lever assembly in the front differential that locks the wheels to the axle broke.. Common problem.. see a Ford dealer for more info....
It uses vaccum to move a little vaccum motor attached to this rod.. check for vaccum at the motor (it has a cover over it) by having someone cycle the 4 wd while watching the motor.. if the rod moves, you have internal problems to front diff.. sorry

shifting to 4 wheel high is ok while driving. the switches on the dash are a constant problem on these trucks. most likely and common problem.

Get under the truck and try drenching the transfer case linkages with good lubricant. if a good lube or even disassembling and reassembling the linkages doesnt fix it then you will have to disassemble the transfer case. one of the shift forks sound jammed and depending on what tcase you have it may or.may not be easy to fix.
