Monaco dynasty frame/suspension failure with pictures

[Miles_of_Smiles]

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?

Thanks for posting pictures. I crawled under mine tonight and all is fine but I have half the miles on mine. I cannot tell if the passenger side is broken all the way around or is the inside still intact? I can understand why the X brace broke (in the weld) once the side arm broke. The torque from braking and accelerating is controlled by these trailing arms so have you had to get on your brakes really hard very often? BUT the way they have broken looks to me like it was from side to side force??? I would check the bushing in the drag link that controls side to side movement of the drive axle.
Since I plan on keeping my Dynasty for many more years I may get motivated to weld 1/2' by 2" flat stock to the front of these tubes at the front or back in the broken area or may a V to the outside.

Both sides are broke. They are not broken at the weld. Passenger side has been broke for awhile, has some surface rust at break. Shop wants to replace with thicker material, it is 3/8ths thick square tubing now. They will start cutting them out tomorrow. These two brackets carry all the load from the lower torque arms. Does anybody else have this problem?

Was the damage due to towing? Or just age?

Monaco won't pay for it.....:W....before and after pictures posted here and on IRV2 would certainly be helpful.....Dennis

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?

Good luck Lee, please let us know the outcome.
I will be going under and checking mine right away. Macktee

Thanks for the replys

I had George at Champion take a look and said it was to big of a job. I have an appointment Monday morning with Botts Welding in Wood stock Il. I am hoping for the best.

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.

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.
