Rubber bushings provide good NHV isolation and articulation, however rubber compresses radially, this causes a  bouncing effect and can leed to wheel hop, in heavy cornering it also causes rear steer variables.
 Replace you rubber leaf spring front eye bushings with PTFB's Spher-O-Bushing will eliminate radial movement and free up rear suspension movement making sway bars and shocks adjustments much more effective and predictable.
