Rear, Step #2 Shock Assembly: The pivot ball (#4637) has significant binding in the shock eyelet.
This may sound odd but it works for me. Slowly remove and reinstall the shock over the pivot ball until the binding is gone. You an also squeeze the outside of eyelet lightly with a pliers to help free it up.

Before installing the side links on the car, I install the pivot balls then tighten the screws until the the gap in the link is closed. After that I set the links aside for a day or two. Before installing the link on the car, I remove the screw completely and spread the gap with a flat screw driver. Spread the gap until the pivot ball is loose in the link.
Install the links on the car and adjust the link screws so the link moves freely without feeling loose.

Compress the spring fully onto the perch. If you fell a click in the spring, slowly turn the spring clockwise until the "clicking" stops.

Heat your reamer with a lighter and ream the pivot balls. This works for me.
If the pivots are still tight, install the pivot balls and work the kingpins around in each pivot. They'll free up nicely.
