I ended up finding that there was a slight amount of play in my horizontal stabilizer. The play was coming from the rod end bearings. What I did to resolve this is to add a half turn clockwise on both rod end bearings. I am still able to freely slide the bolt through the rod end bearing and there is not any bending of the horizontal. Since making this adjustment there is no more play in the horizontal either on the ground moving it by hand or in the air.
