If your brakes are still good you can just replace the hub and drum assembly. What you should do is check the drum and try and see or feel if there are any grooves on the inside of the drum. If there are then that would be the issue and you would need to replace the assembly. Based on your previous info, a 5,200 lb axle with Bearings # 25580, # LM67048 and Grease Seal # GS-2250DL, you will need the Dexter Trailer Hub and Drum Assembly - 5,200-lb Axles - 12" - 6 on 5-1/2 # K08-201-97. view full answer...
