I'm guessing those are Lippert axles? They look like 3" tubes with 10" brake hubs? If so, they're rated at 3500 pounds. All that information should be on a sticker located in the center of each axle beam.
Lippert just announced a 6 year warranty on some of their axles, but before that, there was a 3 or 5 year warranty, depending on the model number.
You might want to do some research on the length of your warranty and hopefully, Lippert will "spring for the repairs" (pun intended)....
