Hey Troy, I am thinking that your axle is rated for either 9,000 or 10,000 lbs. The # 28580 inner and # 25580 outer bearings are the sizes for what we call a #99 spindle. The #99 trailer spindle is typically found on 9,000 lb and 10,000 lb axles. It is also most common for dual wheel trailers to use 9K or 10K axles. The 3" axle tube and 8 lug wheel also points to 9K or 10K.

We do not carry any axles or spindles of this type, we can get you new bearings and seals though. You can use part # 28580 for the inner bearing, # 25580 for the outer bearing, part # T51153 for the grease seal, and part # 6-96 for the spindle nut.
