F350 Locking Hubs Squeeling?

    I've been noticing a noise coming from the front end of my truck(2001 F350 7.3). It only happens in 4 wheel drive, no matter if the hubs are locked or unlocked. I had someone else drive the truck back and forth so I could try to record a video of the noise. I did not hear the noise over the engine. A minute later I got in the truck and started plowing and heard it in the cab.

    The noise is a high pitch squealing that only happens at low speeds. They also almost feel like they're "binding", but I'm not sure if that's just the 4 wheel drive or not.

    Also, at high speeds, the hubs sound like they're grinding whenever I'm off the gas, A.K.A slowing down, doesn't matter if I'm coasting or braking.

    So I guess I'm asking, is this just the hubs, or could something farther along in the 4 wheel drive be causing this? Thank you for any help, I just want to now before I go buying parts!

    I'd check the u-joints.

    Had to replace mine last year. Check the front drive shaft to to see if the are rotted out too.

    I just looked at them, didn't really know what I was looking for my there isn't any play in them.
    I tried pulling the locking hubs out, but they were stuck and couldn't get them. Does the truck have to be in 2 wheel?

    If they are locked that's why you feel that binding when you turn.

    Ok so that's normal. What about the grinding/binding while slowing down?

    Did the brakes a few months ago. It's not them, it only happens when I'm in 4x4.

    is it a rotational type squeak??? or a steady smooth squeak??
    how to ck ft driveshaft--------unbolt it from axle,move it in and out (the black part) if it dont move,,it needs lube.
    move the front u-joint around and see if it binds or is "clicking"-----bad

    It's a steady smooth squeak at low speeds. I'm gonna jack my truck up this weekend and see what I can find.

    Could be the needle bearing on the back side of the spindle. Mine did that, made a nasty sound..low pitch grind. Take apart like you would to replace axle u joints..you will see the needle bearing on the axle side of spindle. Most neglected bearing on most trucks, (at least mine, that is)

    It does sound like the stub shaft bearing in the wheel bearing assembly. Make sure to check the shaft as well.
    This is the bearing B2110 from Napa.

    It is located in the wheel bearing assembly.

    Pulled the left hub off today and found a lot of metal shavings. Cleaned it out but haven't tested it yet. I think it just something in the hub itself.

    I would think that metal shavings are not a good thing and would dig a little deeper before you go out to plow and rely on the truck. JMO
