Good luck with customer service if you have an issue with what you order from etrailer. I have a story on request. Ask me how I know.etrailer.com
They offered a brake controller that I needed,, WAY cheaper than Amazon.
Also check Amazon, and eBay,,
That ENTIRE NEW trailer only cost $450 four years ago,,,,,,,,,,,,,,,,,,,,,,,,,, Northern keeps the axles in their stores,
I never saw a utility trailer axle at Northern that was over $100,,,,,,,,,,,,,,,,,,,,,
Prices are up, but 4.5X seems a little steep,,,,,,,,,,
