2011 Axle broke! Need info!

[PDX David]

Well, at least you now know why it failed. I don't think LL or subsequent owners of LL should be allowed to get away with a serious safety defect like this. I hope you file a report with the NHTSA and also contact KZ RV. As far as I'm concerned they owe you an axle plus installation.  With a safety defect this serious, it's not a warranty issue, it's a potential recall issue.

I did file a report with the NHTSA on my problem because I too consider it a recall issue. I never heard back or know what became of it, but also never got a letter as a registered LL owner informing me of a problem. So, another similar report just might move the needle.

And I strongly second the recommendation to contact KZ-RV to report the problem and seek their "making it right" no matter the age or ownership of the trailer.  I'd do this before spending your own money on parts or repair as they will - once they accept responsibility - want the vehicle inspected and repaired at an approved dealership.  Took me about a week of back and forth to get their approval to take in for an inspection, which led to a warranty claim and repair.  And according to the dealer service rep, when he called KZ to report the undersize axle he's never gotten such a quick "approval" of a warranty repair. Which I interpret to mean that corporate understands this is a serious safety issue.
