During last October's TC visit, it was noted that the clevises at the horn end of both my aileron and elevator trim rods had some horizontal play in them. To fix this, I installed two more washers between each clevis and the horn it attaches to in addition to the two washers already installed on the outside the clevises. This results in no horzontal play in either trim rod.
New washers for the clevis attachments - two per clevis.
Elevator clevis with the additional 2 washers installed.
Aileron trim clevis with the two additional washers installed.
