That's good news that the root of the problem has been discovered. Welcome to the dark side of TT ownership... Some of us have similar stories too unfortunately, so you are not alone. Google "undersized Lippert axles" and you will find lots of info. and personal experiences, like this one for ex. iRV2.com
On the tire and axle rating, you need to deduct the tongue weight. If the GVWR is 7675 lbs and say TW is 12% (normally in 10-15% range), the load on the axles & tires is 6754 lbs. That's cutting it pretty close on the axle ratings. However, if one side is heavier, the tires on that side could be overloaded and if one axle carries more weight than the other, an axle could be overloaded. I would say that the axles should have been the next size up.
Forget about FR, esp. if outside the warranty period. Don't count on the dealer to help on anything at this point whatsoever either. The usual process is that a factory doesn't get involved anyway and you will get a redirect straight to a third party supplier like Lippert anyway. I would get together enough supporting paperwork from the axle shop along with serial numbers on the axles and info. on the tires. I would ask them to put in writing what they find the cause to have been. Send it to Lippert and follow up by phoning them. Also try contacting the axle manufacturer. Maybe you'll get lucky.
If you upgrade to 4K axles, I think you can still use the brake/hub assemblies and 5-bolt wheels, but needs to be checked. If not, the cost would obviously go up a fair bit (if having to pay for all the work).
