rattle under drivers side

[kurbs]

my 2002 Yukon has been an awesome truck since i bought it, the only maintenance being oil changes, but from under the drivers seat or somewhere, we havent pinpointed it, there is a rattle. my son suggests i simply crank the radio, but that can't always happen and even o n slight bumps it squeaks and rattle... its driving me out of my mind... any ideas?

Torsion Bar Bushing is possible...
