01 4x4 engagement problems
When I turn the switch on the front wheels don't engage. I replaced the two vacuum solenoids on the firewall no change. I replaced the actuator motor on the transfer case and everything worked....once. Tried to go around the back of the house thought I was in 4x4 but front wheels not engaging again. buried in mud. I let it set there overnight. Went out earlier started it and put it in 4x4 and it started puling out front wheels engaged. As soon as I gave it a little gas the front wheels became disengaged and it wouldn't go anywhere. I made several more attempts and no luck. I did the vacuum test where you turn the heater on panel and if there's a vacuum leak somewhere the heater blower will default to defrost. It passed this test so I'm assuming there is no leak anywhere. Any ideas why it worked right after I replaced the transfer case motor and again only after I got stuck and it set in the mud overnight? Thanks for any input, Eddie

Perhaps the vacuum actuator on the front diff is just stiff and rusty. That is how mine was. It worked sometimes and sometimes it didn't. Played with the actuator like in the article I am going to list and now it works all the time. https://www.ford-trucks.com/forums/9...97-2003-a.html
