I was long overdue to re-grease my front hubs and bearings. In searching the inter-webs, I found plenty of videos and write-ups for Dana 60s, but not the UD60 specifically. If you have a UD60, you can re-grease 1 hub in about 1 hour following these steps. Set all parts aside as they will all be reused except the hub seal.
What you will need: Dana 48816 (or equivalent, replaces 37729) hub seals, 2-1/2" spindle nut socket (if you're lucky), high-quality grease, other basic tools.
1. Remove tire.
2. Remove caliper (do not let hang) and rotor.
3. Remove the locking hub cap carefully and set aside.
4. Remove the retaining screw circled in red and remove the gear and spring behind it.
5. Carefully remove the inner retaining ring.
6. Find the end of the outer retaining ring and carefully remove.
7. Slide out the body of the locking hub.
8. If you are lucky, you will have a standard 6pt spindle nut (I have read on other forums that some UD60s have a different nut requiring a special socket). Locate the tab(s) on the lock ring that is bent outward and bend back.
9. Using the 2-1/2" spindle nut socket remove the outer nut. Then slide off the tabbed locking ring and remove the inner nut.
10. Slide off the hub being careful of the inner bearing as nothing is holding it in place any longer. The outer bearing is held in place by the hub seal on the back side. Set the hub on the hub seal side, remove the inner bearing and set it aside.
11. Flip the hub over. I used heavy duty snips and vice grips, being careful of the outer bearing, to remove the old hub seal. This will NOT be reused. Once a side is bent up with the vice grips, I found tapping on the vice grips inward to be quite helpful. Once the hub seal is removed, remove and set aside the outer bearing.
12. There's no getting around it... this is going to get messy! Clean out all the old grease from the hub.
13. Pack the hub with high-quality grease. I used AMSOIL DOMINATOR® Synthetic Racing Grease.
14. Clean the outer bearing, then pack it with fresh grease. I using the grease in palm method. Once packed with grease, place it in the hub.
15. Place the new hub seal on the hub and use something to give you even pounding force to pound it flush. I used and old control arm.
16. Clean the spindle and apply a light layer of grease.
17. Clean the inner bearing and pack with fresh grease. Once packed with grease, place it in the hub and carefully slide the hub back on to the spindle.
18. IMPORTANT - start the inner spindle nut by hand and then torque to 95nm. Back off 90 degrees, and then re-torque to 27nm. I found these specs on another forum which stated they got them from Spicer.
19. Slide the tabbed locking ring and then the outer spindle nut. I torqued the outer to 150ft-lbs. I found varying info on the torque spec for the outer so I picked something in the middle. Once torqued, bend at least 1 tab outward.
20. Clean and lightly grease the locking hub components, then re-install in reverse order (see removal above).
21. Reinstall the rotor and caliper. I'm posting both front and rear caliper specs for reference. The caliper adapter mounting bolts (the big bolts), front 130ft-lbs, rear 132ft-lbs. The caliper mounting pins (the little bolts), front 31ft-lbs, rear 24ft-lbs.
