Question:
Hello, I recently figured out my trailer has morryde independent suspension with disc brakes. My trailer is a heartland bighorn limited 3870 fb. I was wondering if you guys could help me identify the type of rotors,bearings and wheel seals that are on it.

Hello Suny, thanks for reaching out. I can help with this but there is no way to look up your RV to know exactly what rotors and bearings you will need.
The easiest way to determine this will be with the casting number from one of your hubs. There should be a number cast on the back of the hub and in most cases we can use this to pull up any specs we would need.
If you can't make out the casting number, you can try checking the axle sticker. In some cases we can use this to determine what you need.
If that fails, the only option would be to remove a hub and unpack the bearings. You can measure the ID of each one, or try to get the bearing number off the edge. Also check the ID and OD of your seal. I will also need to know your hub bolt pattern and stud size.
Reply on this page with whatever info you have and I am happy to look into it and make some recommendations.
