My toyhauler is a 2013 38' Forest River XLR with ~12,000 miles of travel. I was doing a routine inspection in preparation for a trip next week when I found cracks where the spring hangers mount. I am having a hard time understanding why the mounts cracks. It seems as though the majority of the force would be down, and any rotational force would be out. Instead, the cracks seem to be from an up and in motion. Feel free to share your own experience, speculate on the cause, advise on how to repair, offer opinion on in the manufacturer should cover the cost of repair, etc. Be sure and take a look at your spring hangers before your next move.
passenger side rear hanger - dual axle configuration - FWIW, I had a flat on this side this spring.
passenger side front hanger-
driver's side rear hanger
The last 2 don't show cracks that I can see, but the weld line looks suspect.
