Review on End Flange Bearing Plates for Residential Application by Lagant Wardrick

If you change the springs you should also replace them. It only takes 5 extra minutes to install them (4-5 screws to unscrew and redo. The part is stamped in Canada so I'm guessing it was made in Canada? It was a perfect match for what I had. My old ones Bearings were sealed and dry quiet quietly these new ones are quiet I've heard these bearings eat up so why not take the risk changing them when they're so cheap you have to bend and bang them to break them off they also need to be careful as there are some burrs now.
