How do you tell they are worn out? My stock VX was very bouncy and sloppy on the road and bumps. The tires were shot and 2 of the factory shocks were shot. I put new tires and 4 new Rancho 9000XL's and it is much better but still has that "feeling." I have the shocks on 9-FYI. The sway bar bushings look good but still may update them to the Energy Suspension urethane but the only thing that is left is the torsions and rear springs. I have 134k on it now. Maybe it is the "nature of the VX beast" with the short wheelbase, IFS front and springs in rear but until I drive another one, I am not sure.
