Axle troubles on our 2010, 177

We recently purchased a used 2010 rpod 177 from a private party who had purchased the rpod new. On our second excursion into a remote area near Yosemite several weeks ago, the wheel bearings on one side went out. It was quite an ordeal just getting the trailer safely moved to repair shop in that area, since the wheel nearly came off. According the repair shop guys where the trailer was transported, the axle will need to be replaced. We were told that the original axle is no longer made and that a new one will need to be custom built. When I called the service dept. at the dealership where the rpod was originally purchased, I was told that a replacement axle was certainly available, even if the original one was no longer made: it didn't need to be custom built. The service agent added that we needed to know where the unit was built (how do we figure that out?) and/or get the serial number off of the damaged axle to determine a replacement axle. The service agent at the dealership added that this problem had never been encountered at their shop. She gave us an Indiana phone number to call, which we did, and has yet to be returned. We are troubled. We aren't mechanics and are very concerned about getting the repair job done correctly and with the right parts. Any advice/experiences from other rpod owners would be greatly appreciated.

Thank you for the picture. 

The original dealer of the trailer said the failure was likely due to a lack of wheel bearing maintenance. While I don't necessarily doubt that, we know the previous owners used that dealer for the recommended maintenance schedules. Interesting that they would say that. They added that wheel bearings need to be repacked each year, or after 5,000 miles. I was then given the Indiana number to call.

Right now I am in Ohio visiting family. Once California wakes up, I will try to track down the correct part through the service dept of the dealer (or might you have a recommended one that i could talk to?) and then call the mechanics up with what I've found. Hopefully, I can get to the bottom of this part issue today. I suspect it may take some time to get the part.
