You have to split the case to replace the axle needle bearings.  You came to the right place, as there are several good transmission experts here.  They can walk you through any help you need. There are several good threads in the transmission section.  Here's a current one by some first time transmission students that I suspect is similar to yours. 

 

PS as you can see in this thread, don't beat on the hubs to remove them, you can break the hub or the snap ring or splines at the groove.
