... I have the Miracle caps and one of them (on the adjusting side) has some slop. It looks like there are individual parts available for this; do I need to replace the INSERT BEARING 40680001 or is there a simple adjustment I can do once I remove it?
Answering my own question here, the slop in the end caps is controlled by the amount that the bolt is screwed in. It's not a shoulder bolt, and the final adjustment is held with red Loctite.
I assumed the bearing would be worn, but the plastic washer under the bolt head is what wears (it's not protected from the bolt head) and that creates permanent slop in the system. You can see how the bolt head has chewed into the washer:
I will reassemble with new washers (same bearings) and try to use stainless steel washers under the bolt heads to protect the plastic washers.
