start by tightening your steering box, loosen the nut on the top with a ring spanner and turn down tight the grub screw with a big flatblade screwdriver, hold the screwdriver tight with your hand while u tighten the locknut back up, dont let the nut turning move and overtighten the screw.

that should take some play out of your steering.

after that jack up the front end of the car, use jackstands so u can get underthere safely.

grab the wheel on either side and try wobble it holding at top and bottom of tyre, if it wobbles u can see after that where the play is. also get someone to sit in car and wobble the steering from side to side slowly, while they do that u can see underneath where the play is in the front end, that way u know what needs doing.

test your shockies by bouncing the front of the car, if it bounces more than once they need replacing.
