The driver's side play in some instances can be corrected by tightening adjustment nut shown on attached pic. However from my experience little play is always there and not causing clunk in the steering. In most cases clunk caused by worn double joint. If you decide to try adjustment - mark existing position and turn nut in no more than 1/4 turn. This adjustment is not recommended since over-tightening may cause steering bind.
