not having heard it personally its all just guessing. i've had a rattle turn out to be the center cap of my wheel loose and rattle when i hit a bump. i've also had what i thought was the same rattle turn out to be a loose brake caliper. the best advice i could give would be to jack up that side and see if you can get anything to move with just your hands. tearing it apart and replacing the ball joints, tierod ends and other consumables would be a good time to search and see if you can replicate and at least check all of the other possibilities. the cracked frame would also make the same sound
