Author: Brandon Bias (dyingyak@knology.net) This is something I highly recommend for any person with manual hubs. The entire process is fairly simple and quick. I did both drivers and passenger side hubs in my truck in approximately one hour while stopping to take pictures. If you have any questions feel free to email me, my address is that the top of the page. 1. Start my removing the 6 bolts that hold on the hub case, the black part. This requires a 10mm socket.  2. Carefully remove the hub case from body. Becareful handling it because there is already some greast inside. 
 3. The hub on the left was rebuild about 6 months ago while the hub on the right has not been touched since the truck was purchased in June of 2000. 
 4. To disassemble the locking mechanism set the hub to 'Free', from the backside turn locking ring clockwise until it stops (left picture). From that position push the ring down slightly then clockwise until it is from the handle (right picture). Then the ring and spring will left off and apart. 
 5. To clean the hub handle removed the snap ring from the case. I used the tip of a knife to pry it out from the small hole. When removing the handle be very careful of the single ball bearing inside. DO NOT LOSE THIS! After cleaning and adding a little multi-purpose grease, the unit place the ball bearing back in it's seat on the hub handle. 
 6. Clean the locking ring and spring next. To clean I used some dish soap that cuts grease and the hottest water I could stand. This way it helps to remove all the old grease from the hubs so fresh new grease can be applied. Here is a picture of the hubs re-assembled and freshly greased.  7. When you go back the truck you can remove the hub case and clean it out thoroughly. I chose not to do it this time but will do a write-up when I do. Instead I took a paper towel and removed as much old grease as I could and replaced it with fresh MP grease. If you do choose to remove the hub body be sure to use a brass hammer or punch, if not you WILL damage the threads.  8. If you have trouble lining up the assembly back into the body, pull the locking assembly back out and turn it one time until it lines up. There are only 2 positions in which it will slide into place. After that replace the 6 bolts and tighten them about to about 12lbs and re-check them as always after a couple hundred miles.
