Gelalfett,
All of the shop manuals and supplements Mike B mentioned (except for the 1957 & 1958 Supplements) are available to peruse and use for free at
The Old Car Manual Project as well as a whole bunch of other fantastic resources that are just a few clicks away. The parts manuals can also be a big help as they often contain exploded diagrams that better display how components like your carrier bearing setup go together.
I use the site many times a day and find it easy and very useful.
On a related note, it would help everyone reading/responding to your posts if you would either include the specifics of the truck your are working on (make/model/year at least) in the post itself, or you could add a "signature line" like many of us use that provides details about your truck so you don't have to constantly type in that info.
Just a suggestion that will help you and us.
Dan
