What is this mystery metal vibration / buzzing noise? (see video)

[Moglocker]

Looking forward to the solution to this one as I'm dealing with the same front end issue on the same vehicle (2004 manual 4.0 TJ). I would describe mine as more of a jingle rather than a rattle. The teen with better ears than mine describes it as a coin-like jingle.

Mine was making this noise,it was a bad caliper

****SOLVED*****
This noise was coming from the passenger side coil spring… right towards the bottom of the spring 2 of the coils would start rubbing against each other at low speed/rpm! I bought some spring compressors and coil spring insulators so now the coils don’t rub directly!! Gone! No more annoying noise and turning heads in parking lots!
Hope this helped! Long journey!
