Question:
I have a 2010 Harmony 21 FBS Aluminum Superstructure AX5 by SunnyBrook. Dual axle. Trailer is 3800 pounds. Looking for new wheel bearings. Any help on correct bearing size would be appreciated

Hey Gary,
What I'm seeing is that your 2010 Harmony 21FBS will have 3,500 lb axles so you need the Hub Bearing Kit # BK2-100. I wasn't able to find anything definitive about this though, so I do recommend checking the sticker in the middle of one of your axles to verify that weight rating, and be sure to let me know if it's something else.
Your trailer has a unique weight rating which is why I wasn't able to find something concrete.
Have you replaced bearings before, or do you plan on having a shop do it for you?
