If the ends and links are good, the steering box has some adjustability to account for internal wear.
Open the hood and look down at it. On the top front you will see an allen headed bolt with a jam nut. Back off the jam nut a turn then tighten the allen bolt a bit, maybe 1/2 to a full turn, then tighten the jam nut again. Be sure to hold the adjustment on the allen bolt while tightening the jam nut. There is a spec for preload on the gear but every one I've seen has so much friction in tightening the allen bolt that the preload is moot. Take it in small bites, drive it, repeat, until the play is pretty much gone. Over torqueing the preload will wear out your steering box quickly.
