Hi. With a plastic insert in the lovejoy joint, misalignment should be less of a problem. I would expect that insert to disintegrate before the bearing goes out. Which of the two bearings is making the noise?
For what is worth, I bought a brand new motor off eBay that came factory boxed. Upon starting it, I noticed the bearings were busted. My guess - and by seeing one of the fan fins slightly bent - is that someone dropped it while being manufactured and damaged the bearings. I replaced the bearings myself with new, high quality ones. Are you sure they gave you a new set of bearings and not just repacked the old ones?
