slide out support broken weld

[gadiy]

I appear to have a broken weld at the end of my living room slide out which is causing the room to dip on the inside and twist the wall trim. Has anyone had this issue and repaired it without the use of a dealer. I purchased this used when I was working out of state. This is out of warranty and I do not have a keystone dealer within 100 miles of me.
