04 Monaco Dynasty 130K miles. I had a noise in the rear suspension for about the last 1K miles. Finally crawled under to take a look. I found the frame where the lower trailing arms attach broken at the frame rail. Both sides are broken. Also found cracks in the "X" brack that attachs to the frame. I am looking for a shop in the Chicago area to get this repaired. I do not have the equipment to repair this myself. Has any one had this problem? If so, who did you have repair it? Lee

We had some brackets fabricated for our 2004 Country Coach Allure at a truck and bus suspension repair shop in Tampa FL. It's like this shop in Chicago: http://www.busntruckchicago.com/ I'm not recommending this business, just giving you an idea of where to look.

It is a known failure point on that year Monaco. They are called the trailing arms. There are businesses that specialize in replacing them with beefier arms. Try doing a search on trailing arms. I am certain someone else will jump in here that has more information.

Monaco RR4R Chassis Trailing Arm Problem

Thanks for the help. I will look into the bus truck place. It is not the trailing arm. The Dynasty is on a S- Series chassis.Lee

NO, the trailing arm issue was NOT on the 8 air bag chassis.Only the 4 bag suspension was involved in the trailing arm design issues.

As Wolf10 stated the Dynasty Chassis was not part of the Trailing Arm Issue.
Champion Frame & Alignment in Elgin (847 742-9294) does heavy truck and Motorhome frame repair. They can be a bit pricey, but you get what you pay for.

It might be interesting to document this repair with before and after photos for others with the same or similar chassis. Was the failure in the weld itself or the heat affected zone around the weld?
