See if you can turn the inner shaft 180* + running it up and down a few times with heavy grease seemed to have helped remove most of the chatter.
Also on some models there may be a zerk grease fitting down on the electric motor area that could use a few pumps. Sometimes it's hard to see down there as it's usually on the back side if it's there.
Good luck.
Good idea on the inner shaft. Maybe I got it 180 out when I disconnected it to re-do the hatch foam. It was operating smoothly before that.
I did grease the zerk, but no fix...
