I've gotta change the drivers side CV Axle, is there a Bearing & Seal that can be changed as well? If so,
any part #'s?

 

You can lookup parts on any number of online Mazda part sites. Enter the details and look for a section like Front Drive axle (or something close to it).

Here's one: https://www.mazda-parts.com/

Then you can search for the part number to find a less expensive source.
