This is the link to the Dexter maintenance manual.
https://www.dexteraxle.com/user_area...ice_manual.pdf On page 48 is the start of the bearing service procedures and there is also a scan link on the bottom of page 48 that takes you to a Dexter video of the bearing maintenance. Also, 50 ft lbs is every time you pack the bearings to do the bearing adjustment, and the instructions tell you how to do that. I guess the link in the manual is no longer active, but this link will take you to the Dexter video.
