Super Duty locking hubs???

[MTBLAZER89]

Anybody with a 4x4 SD know anything about these? My buddy has a noise coming from that area in his 2000 SD. Got the snap ring off, but the hub won't slide out /forums/images/graemlins/dunno.gif Also these have the auto/locking hubs and when in the lock position you can grab the front driveline and spin it. You can see the axles turning in the knuckles..??? Is this normal does anybody know how these work???

Thanks soorry for the FURD questions /forums/images/graemlins/woot.gif /forums/images/graemlins/whistling.gif

There are 2 snap rings one on the shaft, one on the hub.
What kind of sound is it ???
It might be his bearing assy.

Yeah there is a snap ring outside (instead of screws) that hold the dial cap in. Got that ring out and the book says it will just slide out. Found some good info on a ford site, but I am still confused on how the hubs are in LOCK and the axles still spin freely /forums/images/graemlins/dunno.gif

If that's the case, they're probably broken.

Once you get them out you'll be able to inspect the gear that moves and see if it is engaging the hub body.

Could it be the unit bearing going bad? /forums/images/graemlins/dunno.gif The hub is just 1 big piece, it would make more sense if the was niose coming from the bearing.
