Could be something in the ADD system.

Here's a good article on troubleshooting

If you have the ADD system, it could be a vacuum leak. My advice is to ditch the ADD, and throw on a set of manual hubs. Less wear on the front end, more MPG, and less to go wrong with the ADD crap. Just my 2cents.

If it came factory with manual hubs, then you dont have ADD and that means no solenoids.

It has to be a mechanical problem. You have to get out there and troubleshoot.
