bambiajkora Report post Posted January 12, 2013 We have a 2005 Monaco Dynasty w/ auto air leveling system HWH. It used stay level after we park it in our garage, for weeks. Lately I noticed the rear end is sagging while it is parked. The rate of sag is 3.5 inches down in six hours. (left to right stays in level) No issues on the front end. Any of you folks had this problem? What causes this problem and how did you fix it? Thanks bambiajlora Share this post Link to post Share on other sites

wolfe10 Report post Posted January 12, 2013 No, a 2005 Dynasty will not have the 4 bag suspension that had trailing arm failures. Likely you have a slow leak from ride height valve, line or air bag. Use a bubble solution with full air pressure up to check for leaks (using safety stands!). Share this post Link to post Share on other sites
