Hi gurus!<br />Have an '01 Monterey 24' with a 7.4 L Volvo DuoProp. At low speed, or idle, when the steering wheel is against the stop or near it, either side, there is often, but not always a knock that comes out of the rear end. Also, the steering wheel starts jumping back and forth.<br /><br />I don't suppose this is a) normal, b) cheap and easy to repair?<br /><br />Suggestions? <br /><br />Thanks in advance.<br /><br />Dano
