Hi all. Maintenance question: Is there any way to reduce a (very small) amount of play in the rear swinging arm pivot (just behind the bottom bracket)? The user manual says it has sealed bearings and not to touch it.

When I flex a crank with both wheels on the ground, I can feel a tiny bit of side-to-side wiggle between the frame & rear triangle. I've already adjusted play out of the upper fold clip. Is that about all I can do?
