If you have a visible crack in the tension strut bushing and play in the arm when pulling on it, I'd replace it while the car is apart and in the air, a pair of poly bushings shouldn't be much if you wanted to go that route, and I'd do the ball joints on the other side of the arm at the same time as well.
