Wheel/U Joint Binding?

[99BEIGEPOWERSTROKE]

I was checking out all my front end componets when swapping my wheels to my winter set today. With the wheels up off the ground. When I lock in the hubs the front wheels turn fine. But when I turn the wheels either direction and try and spin them the right wheel will not spin. The left will fine. If I unlock hub on right side it will spin but with the hubs locked in and the wheels turned the wheel will not spin. If you push hard it will barley budge but feels like it is binding up. Im thinking u joint is binding but not sure? Does this sound like the U Joint? Any ideas or anyone have this problem before?
Thanks

Sounds like the u joint to me, not the unit berring or the axle needle support berrings inside the unit hub. Mine do the same, need to replace them before winter hits hard...

well with 4x4 locked in your not support to make sharp turns. the u-joints just cant rotate when the tires are fully tired

Ya but with the wheel just turned even like half way it binds up and the wheel wont turn.

also, the front diff is "open" unlike the rear, so one side might spin freely and the other wont, since one side will spin the gears, and the other wont

EDIT: u-joints will always bind, no way around it unless u do a CV conversion. put the wheels straight and lock the hubs, and move the tire back n forth and see if theres play in the u-joint

You should see that your trying to turn the front propshaft & the gears thats probably why. Iv'e changed everything on the front of mine. I even fitted a new steering box only to find out that my front uj's were shot. One side was totaly seized. It made the truck knock real bad occasionaly on cornering as well as other problems.

Put new U joint in mine and all is good.
