Need some help identifying Front drive problem (video inside)

[TylerSVT]

So ive got a 96 B4000 with auto hubs and electronic 4wd.

The truck will engage in 4wd but will not really "BE" in 4wd, like the driveshaft is engaged so i know the transfer case is fine, but the front wheels will not turn at all under throttle.

I took off the driver side wheel and autohub and grabbed the axle with a vice grip while i turned the front driveshaft (truck was in 2wd) and i can easily turn the driveshaft and have the axle not move. I can see the passenger side axle is moving (dunno if the auto hub is f'd on that side too)

My question is, should the axle be moving at all? or should it be locked in and moving if im turning the driveshaft...

So is it my axles? the diff? or the auto hubs?

Well, you have auto hubs. That is your first problem. Sounds like your whole problem too.

So its just the hubs? Are the axels supposed to be able to move indpendent of the driveshaft?

1.Most likely. 2.Yeah, if they were both locked all the time you would not be able turn the truck without a fight. This is the conversion to manual locking hubs- http://cgi.ebay.com/ebaymotors/Warn...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

This may not the best price out there. However, Warn makes the best part for your truck. Very reliable and a snap to install.

Edit: part# Warn 29071. I did not see it listed it that link.
