if its just steering box free play you can try adjusting the screw on top of steering box in slightly but not tight. you need to back off the outer lock nut then you can turn the screw head with a normal screw driver for this slight adjustment. most of the time you will get less free play after this adjustment is made. check all steering componants firstly before doing this screw adjustment as you could have a badly worn part on the steering that Must be fixed for safety.
