Can't steer on 4H with my 2002 F150 SuperCrew.
Good day to all! This is my 2nd time i owned F150 super crew and having some problems. I can't make a full turn with my screw while on 4H. I can only turn it to small degree. Tires will stuck and skid. Also having hard time to engage. Isn't it shift on the fly? I mean i can shift from 2H to 4H without stopping. What parts should look for repair? Thanks

Because they are stupid? LOL Years ago I had a nissan 4x4 truck I was selling and this kid came and looked at it asked if he could take his dad and look it over.. let him take it and he was gone for awhile (long enough to worry me) anyway he comes back telling me the truck is junk because when you put it in 4x4 on dry pavement it binds.. The truck was under warrantee still so I had it checked out and the service writer just laughed. Said that happens all the time..

I know that it is not necessary to use 4wd on paved road but there is nothing muddy near my place. Again my apologies if my ignorance annoys you. THanks

The bind comes not from CV joints.
Please remember that a locked axle turning a turn has both wheels trying to turn at different RPM because of the large difference in their turning radius.
Now what will happen under these conditions?
Each wheel fights road friction, one or both will sprag back and forth and offer resistance to the steering because they both want to go straight ahead.
Late model SUVs may get around this with vairable drives and not act the same way.
You cannot compair a truck with an SUV and expect both to act the same.
In the rear axle that has a traction loc carrier, there are clutches to aleaviate spragging to a large degree.
A truck's front carrier has no clutches.

The only stipulation to shift-on-the-fly, is to be doing less than 60 MPH when you engage the transfer case.
I often put my truck in 4WD when it is dry out. Most of the time it is to back up to a trailer, move a trailer a short distance, or if I am on a steep hill ... but I know better than to try to turn on dry pavement in 4WD.
