Replacement Bearing Kit for a 4400lbs Axle on a  

Updated 03/20/2026 | Published 03/17/2026

Question:

I’m repacking my wheel bearings for the first time. I have a 2021 Winnebago Minnie travel trailer with double Dexter 4400lbs axles. I’m getting an assortment of conflicting part numbers for back seals and the bearing cones. I have a pic of the axle it shows a number132274976. I wanted the parts before tearing apart to get the numbers. Can you help?

Hey Rick, I’m happy to help.

Based on your trailer having 4,400 lb Dexter axles, the bearing kit # DX86ER is what you would need for your trailer. This is the only bearing kit available for a 4,400 lb Dexter axle.

What kind of trip are you prepping the trailer for?

Yes, I too had different numbers as well. The package numbers were different from the parts. I had to return my first kit. I had to pull the old parts and get the numbers off of them first. Then I ordered my new parts.
