Well, that turned into a bit more work than I thought. The front part of the shaft drive kept coming loose. I called the manufacturer and they suggested adding some loctite red. I ordered some of that and put it on there today. Unscrewed the loose part as far as it would go, cleaned it up and add a lot of loctite and tightened it as hard as I could. Now I will let it sit for 24 hours and test ride it tomorrow to see if that worked. Also, still waiting on the grease.
