You can't have a hexagon shaft in a round hole with nothing to keep it in place. We turned down the shaft so it was round and it rides nice and snug in the bearing without any play. The top block is the new one I had the shop fix. I cycled the slide maybe 4 times and that is what it looks like already. He put a bandaid on the problem it was going to fail again soon. Lippert needs to do a recall on this design. The way they built it it is going to fail. If you have this slide design you should find someone with a mill and a lathe and fix it the right way. Also do this yourself it took a day to replace and repair both ends of the slide not the months it takes the rv shops.
