LCA pivot shaft

I vaguely recall reading that the poly LCA bushings are no longer sold. Many people here fear them, saying that the only thing securing the LCA axially would then be the little wire clip at the rear of the torsion bar. I wouldn't be overly concerned since the T-bar is always under much load and unlikely to slip axially. Still, most cars use twisting rubber bushings, so I see no need to slide. The poly bushings are supposed to add stiffness and perhaps last longer, though the sliding may make them wear. We will know as people like you report over the next 10 years.
