Hmm I think your mechanic is domestic/truck oriented as per the words he used.Torsion bars are tc rods (Tension Control rods)struts are your shocks. You can either replace the rubber bushings, with either energy suspension,pdm,nismo bushings. Or buy all together a new set of tc rods. The rubber bushing wears/rips apart and there is more flex. Example.
