You first need to determine where the slack is before throwing a bunch of parts at it. You may need to take it to a reliable front end alignment shop and have them give it a thorough lookover. Your sector may not need adjusting or replacing. Sometimes a tow out condition will make them head off one way or the other and is easily adjusted. You can check it yourself with a tape measure. After already replacing some front end parts it needs to be realigned anyway. You will probably be money ahead by having a front end shop look it over first.
