Joe when we bought our coach in 98 we heard a rattle under the floor. when we put new steer tires on the guy said there was a broken shock, hence the noise. After a new shock was added we drove the bus for a few thousand mile and another broken shock. The shocks wern't the right ones for the bus, Called prevost and ask for the right number of shock for the front, had my tire guy match the number up and it was fixed for good. So check to see if the right shocks are on your coach.
