Not sure about your model, but on my 2nd gen, the steering gear box has an adjusting screw on the top for increasing/decreasing freeplay. There are two fittings on the top of the gear box, one is the bleeder valve for the ps and the other larger one is the adjusting screw. Might wanna check your manual for freeplay specs.
