If your stitches are now normal perhaps you need a drop of oil somewhere?? Again, not familiar with your machine but noise generally equals lack of lubricant. If it's a 'self-oiling' machine it may just be time for a service. Check your manual even if it's supposed to be 'self oiling'. There may still be a couple of spots that need to be owner-serviced.
