If you are chasing a shimmy, I would suggest doing both control arms (i.e. tension strut and the 'other' one) and tie rod ends all at once - that way you have changed all bushes and ball joints in the front.

I say this because none of my ball joints or bushes showed signs of play, but once off, you could see the ball joints were gone - they wiggled freely.

I did mine in stages - tension strut first - still not right, other control arm - still not right, tie rod ends - finally felt right up front. I should have just had the whole lot done in one go for ease.
