has anyone had problems with their steering system. it feels like something is loose in my system. the linkage coming out of the firewall seems like it might have a small bit of play in it. the pitman arm rubber boot has burst from the dealer overgreasing. the steering wheel has a bit of up/down movement in it if you push hard. question: has anyone had similar problems? or has anyone had problems with their pitman arm or steering gear unit? thanks. scott.
