Rubber.



When you tightened down the LCA pin to the K-member with the car level side to side at ride height, the pin slightly moved or the adjuster arm socket was not 100% in contact with the screw adjuster pin. Tough to see when the car is on the ground.

The rubber bushing is directly pressed in the adjuster arm housing. And then the pin is pressed directly to the bushing. So wherever you bolt the pin into the K-member the adjuster arm will be clocked in that same position at rest with no load.

The rubber flexes with the LCA moves up and down. Just try you best to get it neutral flex at ride height zero position to minimize the amount of flexing at extremes of travel.
