Truck making strange noise... Help!
2007 XLT 5.4 Supercab 4x4 70000 miles
Hey all. My truck is making a weird noise. It seems to be coming from under the cabin towards the front. It made the noise for a few weeks about a year ago and then it stopped until the last couple weeks. It sounds like if you had a spring wound up and you released it in a coffee can. Sometimes it will only last a second and other times maybe 15 seconds. The truck drives fine and I can't seem to reproduce it for a mechanic. It just comes and goes. Any thoughts? Thanks.

I seem to have the same noise (like dropping a patio screen with nylon rollers, or a can full of BB's) and posted in Maintenance. So far, just a suggestion to duct tape trim one piece at a time until you find a loose piece. So for today, I can positively state that it is NOT the trim strips that go over the roof just above the windows.

Kind of sounds like a 4x4 issues. I.e. Loss of vacuum to hubs. I had the same thing. Sounded like you describe. Get a hand vacuum pump with a gauge and test the system. Can be rented from auto parts store. My 2 cents!
Tons of forums on here about it. I replaced my solenoid for $35 and it's all good. 4x4 works great.

When the noise happens, immediately switch to 4WD (it won't hurt anything as long as you are not making a sharp turn and are under 50 MPH, even on dry pavement). If the noise goes away, see: https://www.f150forum.com/f72/how-di...72/?styleid=14

It's on the firewall passenger side behind battery

If that's the case, unplug the solenoid electrical connector. This won't hurt a thing other than costing you a little fuel mileage and your 4x4 won't engage. You might have to drive it for a few weeks to make sure the noise doesn't come back, or you could just go straight to the tests in my How To....

Well I jacked up the front of my truck one side at a time. Both shafts spin with the engine off and they don't spin with the engine on. With the truck running I removed the vacuum lines and both wheels spin. Seems from what I am reading everything is working there. There is sufficient vacuum when the truck is running to keep the hubs unlocked... correct? What should I do next?
Thanks for the help, I need a break. An easy fix would make my month.
