'01 4wd shift on the fly problem

SITUATION - 15 mph in a pasture field, soft ground

PROBLEM - Shifted my 2001 F350 dually into 4wd high (electronic shift on the fly with hubs set at automatic) and front wheels locked up and would turn

Clues - got her back onto the gravel lane and could hear grinding coming from front hubs. would not dissengage after flipping swtich on dash. finnally dissengaged after manually swithing hubs from auto to locked and back to auto.

Any help with diagnosis would be greatly appreciated.

Re: '01 4wd shift on the fly problem

Welcome to TDS. First thing I would do is remove the hubs and clean them up. It is real easy to do. Try a search and you should find how to do it. If you don't just post back and we'll find it for you.

Re: '01 4wd shift on the fly problem

Also check for leaks with a cracked vaccum hoses that go to the hubs. Most change them out to SS hoses from www.dieselsite.com , makes a big difference. Also, cleaning and greasing the hubs, is a good idea.

Here is Gruzzle's Hub Lub which is pretty intensive. I've never taken mine that far apart. I just flush them with WD40. Works for me.
