I've got an 05 f150 2wd with a 3" leveling kit in the front. If I drive without music and my windows down, I can hear a jingling noise under my front end. It's not constant, but frequent enough to be more than just an occasional thing, and only happens when I go over bumps that cause the suspension to flex at different times. It sounds like loose washers rattling against each other, or small sleigh bells. I had the same problem with my last truck (a lifted 1993 f150) but I could never pin point the source of the noise. Has anyone else had this problem and figured it out? If so, what is causing the noise, and what is the best course of action for fixing it?

 

I would just go under there and start checking all the nuts and bolts..doesnt hurt to check anyway. use can use a small hammer and tap on them..youll eventually come across something loose.
