There is a service notice on the bracket that holds the trim end of the cable. Check with Van's website.
The fitting that holds the cable on to the elevator is a small steel plate with a nut welded to it which, in turn, is riveted to the under skin of the elevator. The original fitting was welded on
ONE side of the nut and had a tendency to break off.
The new fitting has the bolt welded on
BOTH sides of the nut, that is fore and aft. You might be able to look up there and see if it has welds on both sides. If it does not, you can order a new one that replaces the old one. It is a little bit of a PITA to replace but doable. When I did mine, I took the old, one weld fitting after I had replaced it and just barely pushed on it and it snapped off.
It MIGHT be where your play is coming from. Crawl under the elevator and move the trim tab. If the nut the cable runs through moves, that could be the problem.
When you manually move the trim tab itself, there should be NO movement without a
noticeable resistance. You should
hear/feel the trim cable move in the cable housing. If it moves half inch without resistance, that is a problem....... What do the clevis fittings at both ends of the cable look like? Are they ovaled out? Is the horn on the trim tab loose or ovaled out? Just thinking.........
