Now I dont know if this has always been this way or just noticing the play. What could it be? I dont have any grinding sound like a wore out bearing and it has no slack from left to right. Any sugguestions? Maybe just tighten it up?

Thanks sheeple

There are also needle bearings inside the "dog bone" holes in the SA. Also the holes in the aluminum "dog bone" can get all hollow out...also check to make sure the spring isn't loose when you have 0 pressure on the suspension (not hanging weight or actual bike weight). Clapped out bikes develop slack in the rear suspension that is noticed most at BP.
