I am pretty sure this is not the case, however, I would inspect the coil spring on the side the noise is coming from.
On my 04 F150, which had some rust issues, and was taken offroad, I cracked a coil spring, and actually had about one and a half coils, at the bottom, split off and resting inside the remainder of the coil.
This caused significant noise and loss in ride quality however.
Still something that I would check, as a visual inspection will let you know for sure.
