4x4 not working

Asked by Jan 23, 2016 at 09:17 AM about the 2000 Ford F-250 Super Duty XLT 4WD Extended Cab LB

Question type: Maintenance & Repair

I have a 2000 SD with manual t case and manual
hubs. I just switched out the factory plastic hubs
with WARN hubs. I engage the T-case but front
wheels will not spin with hubs locked.

So either the transfer case is not operating or you messed something up replacing the front hubs, this is assuming the front driveline is still there and the ring and pinion are intact. There is a possabality that you broke and axle shaft. Take it out of 4WD, set the park brake and or block the rear wheels, jack up the front high enough to clear the ground, then spin each front wheel by hand as you turn the hub in and out, you should be able to hear and feel the hub engage and disengage, you should also be able to see the small u-joint turn when the hud is engaged and stop when not, both hubs have to work for the front axle to become live otherwise the spider gears just rotate around the live axle instead of delivering power. Make sense? HTH

Makes sense yes. I had a passenger side wheel bearing go bad it over heated and melted the plastic hub that is why they were replaced. Everything worked prior. I must have missed something with the hub install. I just don't know what it could be.


If it melted the hub it is highly possible that you missed a little piece of plastic from the old hubs, it would only take a small sliver of plastic in one of the groves and the hub will not click in. Been there done that on one of my Broncos.

Looks like I am taking them back out in the middle of the blizzard. Thanks for the ideas.


Well at least you weren't out in the boonies somewhere and really needing 4WD cause you just got stuck.

No I'm just stuck in my driveway and not out plowing
