Y axis carriage upgrade  

Y axis carriage upgrade

I have been having noise issues with the y axis, ever since I built my mk3s a couple months ago.  I have replaced the rods and bearings, adjusted the belt, checked every bolt, I think I have tried everything.  After re-angling the bearings so the balls are perfectly vertical, it worked great for a night, now the side sounds like a dying puppy.  If I remove the belt it glides smooth as butter, but with a tiny bit of force/resistance with the belt, everything goes wrong.  And every time I hear a noise, it always comes from roughly the same place.  It seems to come from the singular bearing on the right side of the carriage.  Depending on how I apply pressure changes the amount of noise, but it's always from the right side.  I believe it is from how easy it is to flex the right side with the fact it isn't balanced with a second bearing, like the left side.  

I was thinking of trying this plate out using a fourth bearing on the right side, so it is "perfectly balanced, as all things should be."

Unless there is one that is prefabbed somewhere that I didn't see, it would probably be a kinda expensive piece to get machined, but I'm out of ideas.
