The importer has a replacement puck kit that you can buy for about $130
Instead of a cone-shaped spindle it has a non-tapered shaft of about a half inch diameter. The new puck then locates snuggly onto the shaft eliminating any lateral movement when the assembly rotates.
It all feels much more solid. You'll need a small bladed screwdriver to pop out the old tapered shaft and some epoxy/adhesive to bond the new shaft in position.
Here's a link to their website
