I have a 2004 F150 4x4 and i have this annoying rattle sounds like its coming underneath the driver's seat and it only rattles when i am going slow over bumps anyone else experiencing this issue? i am thinking it may have something to do with the steering column but i am not sure

 

Check up under the passanger seat. I know on mine there are two quick electical quick connects and one bounces when I hit small bumps and makes a high pitch chirp. I used velcro on the frame and the quick connect(to be able to loosen at later date if needed) and all is well.

I have a Screw by the way.

 

the in cab jack for changing tires was rattling pretty bad in my reg cab, i stuffed a towel in the jack pocket and that solved.....same deal with the rear wall plastic

 

check your tie rod ends gone through 4 of em so I know the sound, also get under and smack your sway bar w/a rubber mallet (feels better than your fist) I had an end link go and it rattled like crazy..
