Jasemas's diagram link shows that your shocks have a forked end at the bottom with a bolt that passes through it and which also passes through the lower mount (bush). In this case that bush is pressed into the LCA (lower control arm). That bush is a press fit in the arm and can be replaced. SnoopG's photo shows the other type of shock bush that is in the shock itself, referred to as "eyelet type", non-replaceable.
