You already did all of the work here by finding the bearings. Since you have a # 25580 inner and # 15123 outer bearing the Easy Grease Trailer Hub and Drum Assembly for 6K Axles # AKHD-655-6-G-EZ-K will work as a replacement.
The only other thing to match up is the bolt pattern and this has the same 6 on 5-1/2 you currently have. If you want replacement brakes as well you can use the # AKUBRK-7. If you don't have a lockout and need free backing brakes then we also have the # AKFBBRK-7. view full answer...
