clean the ball joint boots and look carefully if they are black rubber ones they are not lemforder joints, lemforder joints (which is the ONLY joint one should use in these cars) have white plastic boots.

If the joints are not lemforder you can be assured they are worn out in 2 years. - use a large channel locks to check for up down play - you are supposed to hook the pliers on the bolt and the ear on the joint boss in the arm, squeeze hard - if you see it move even a hair your joint is shot.
