Torsion Bars

Has anyone experienced a problem with the torsion bars causing a metal to metal sound when driving the truck? I've gone throught the entire front end and cannot find the problem of the noise. Thanks in advance. Replaced Ball joints(lower) shocks and outer tie rod ends. Sound seems to be coming from under my feet and same on the pass side.
