Has anyone successfully identified the real problem in the legs. Applying Pledge isn't the proper fix, although probably part of it. I've popped apart everything I can on the legs. What it seems to be is the feet not resting flush. They seem to want to push inward, forcing the legs apart. I've trimmed any flash I can see. I'm just not sure what part to try sanding to make the feet sit how they're meant to. The swinging arm for the feet? The surface of the foot assembly that rests on the leg? Help?
