It's really not that hard at all. I saw a article in a magazine (think i still have it somewhere) and tried it. The box i was using had bearings in it. The only thing i did was pull it apart, cleaned it really well, put in the new bearings and seals and filled it with grease. The hardest part was adjusting it and that's a piece of cake. Just use a inch pound torque wrench ( the needle type not the click type ) to adjust the drag as you are turning the box. John
