Question:
I have an RV with Dexter axles. The label shows them to be 4400 pound axles. I’m looking for which bearings and inner seals go with these axles. I have two numbers off the label on these axles. One of them is 275-2339, and the other one is 021-7158. These numbers are on the same label, but I don’t know which one is relevant for making the right bearing and seal choice.

Hey Steven, we have the individual components of a bearing kit available for a Dexter 4,400 lb trailer axle but since it's a rarer axle capacity we don't have a bearing kit. So for a Timken set you'd want the part # TMK49FR and # TMK56FR and then for a grease seal # 58846.
