Hi Don, I can definitely help with that. I know when it comes to bearings and seals it is easy to worry about tearing everything apart and then finding out you ordered the wrong parts, especially when you just want the trailer ready and reliable.

Since it has an EZ Lube style hub, the key is identifying the exact bearing and seal sizes so we can match everything correctly. The most accurate way to do that is to either check the numbers stamped on the side of your existing inner and outer bearings, or measure the spindle with digital calipers where the bearings and seal ride. The measurements need to be precise, down to the thousandth of an inch, to make sure we get you the correct inner bearing, outer bearing, races, and double lip grease seal that will work properly with your EZ Lube setup.

Once we have those numbers or measurements, I can put together a confirmed match so you are not guessing or doing this job twice. What bike are you hauling on that trailer, and where is your next ride once you get the hubs buttoned up?
