Both the Upper and Lower Control Arms pivot on the Elasticity of the Rubber; not on the Bolt.

Why believe that: The Bolts show not sign of wear in the area they would have to pivot on, they rust up, if something move on them they would need to be lubed, the thin Aluminum Sleeve would wear out fast, and there would have to be some end play in the assembly like there is on other Cars where the Control arm actually pivots on a metal to metal.
