yeah hi,possibly all your steering column bushes are worn,if you know of its history and these have not been replaced then i would,relatively easy job,and ford still sell all the bushes,also check your sheer bolt on top of your column,to see if it is missing,this will make your instrument stalks move when your wheel lock is on giving the impression that the whole steering column is loose,for vibration check your discs,also another vague steering issue is that the wheel bearings could be worn,ok,thanx???
