I can't believe that this is the only post that describes my current issue but is NOT any of the recomended things to try to alleviate the issue. I have narrowed it down to the needle bar area. At the beginning of the downstroke it sqeak's. It started today, slightly and not every stitch, but has got worse regardless of being properly lubed, with or without thread. There were no accidents and the machine is tuned to the same as the day I got it. I have tried everything I know to do (and I'm not new to sewing on these machines) but it has me stumped and hoping the good folks here have a recommendation to point me in a good direction.
