So I just happened to park the 743 for a moment where the bucket was resting on a piece of 6x6 about in the middle of the bottom of the bucket. When I pushed on the edge of the bucket it rocked easily, meaning there was decent amount of play in the knuckle of the tilt cylinder where it attaches to the back of the bucket. Is that a rubber grommet or bushing that is intended to have play or is something worn out?
