LCA pivot pin loose in bushing problem

With OE style bushings the pin needs to be a press fit into that metal inner sleeve. If it’s not, they’re junk.

The requirements change if you change bushing materials, but even for the poly and Delrin bushings the pin should fit tightly into the bushing (tight slip fit). Any slop between the bushing and pin is slop in your suspension and will amount to a loose alignment. Plus wear out the bushings faster.
