Hi katrina,

You did not mention if you pulled just one wheel and hub or both. If only one, pull the other side and perhaps the parts you are looking for may be there for a positive ID-assembly?

Do you need an exploded view of the front hub? If so, please let me know your truck model identification found on the following link:

I may have a good exploded view, and part numbers of what it is that you are missing.

Hope this helps,

Dale
