Well, I had a clunk on the drivers side. I had heard it about three or four times so I was not really concerned, but it made me wonder what it could be because I had never heard that before. I was lubricating all the fitting on the chassis and I noticed that on the front sway bar one of the short rods that is attached to the sway bar and on to the frame had a rubber groumet washer missing right where it goes onto the frame. That is what was causing the clunk I was hearing on rough roads. What it is doing is hitting medal on medal causing the noise. I ordered the groumet through the internet for a cost of .99 cents plus $9.00 shipping. Maybe that is the same problem you might have on your coach.
