4x4 is not working.
2004 Ford F-150 Lariat crew cab I just got his truck a week ago. Bought it off my family, and they said the 4x4 worked, I never put it in just cause I have no use for it yett. But long story short it set outside all night it was 20° That night I went out the next morning started it. Let it warm up for 3 to 5 min went to pull out and it sounded like a pop can in a bicycle tire in the front end. It seemed like something was striking another peice of metal numerous times. So I went a little further 500 feet At 2 miles per hour and finally said I can't drive this like this so I was thinking to myself. Why not for ****s and giggles put this in 4x4 in try that. So I did and everything was fine again. "BUT" now my front 4x4 does not work. Please help me!!

Of course I've looked under the truck. Nothing shows to be out of order. I parked the truck 8 hours prior in the driveway. Came back out the next morning and it seems like the 4 wheel drive was half engaged. "Note" I never touched the 4x4 switch, but It seemed like it was rubbing against another peice of metal in the front differential. So I thought what the hell it can't hurt to put it in 4x4 and see if that makes it stop And it did make it stop. Now the 4x4 does not work

04... replace the IWE solenoid on the passenger side firewall behind the battery...the new solenoid will have a rain hood built on to it to prevent water intrusion...water can get into the vacuum line and Freeze...this will prevent the wheel ends from un-locking or a partial un-lock...which is the noise you are hearing...when you select 4WD the wheel ends vent this vacuum and engage and your noise goes away.

Good to hear.. the vacuum pump test would of found a bad IWE...some people don't have the money to just replace parts during troubleshooting.
