crawl underneath with a torch and check out all your steering ball joints for wear.also check out all your other bushes...gotta replace them sooner or later...best to do it in one go..if one bit is gone quite often the rest of them are on their way out too so check all steering linkages, ball joints and bushes...get some eurethane bushes..newer type(teflon coated-no grease nipples)sealed ball joints, tie rod ends etc. .........and enjoy
