I just completed a cross country trip to California. About 80 miles from my destination I pulled in to fuel up. I noticed something unusual about the trail axle wheels, they were slightly bowed out. I raised the axle which somewhat helped while I limped into my destination. I took the attached photos which show the breaks in the metal on both sides of the coach. Is this something that can be fixed such as welded, or does it require replacement? I appreciate any help or suggestions you can provide. Roger
