Usually the cheap rebuild kits don't have the axle bearings, however the axle bearings are normally available at parts stores. You probably have everything for the diff but missing stuff like bearing #9 below. I've had great luck measuring the in/out/width on a bearing, hitting google to find a number to cross, and then calling the local parts store. Bearings are only about $8 in a parts store and are pretty easy to find.
I have a DS 650x available. Garage kept for its entire life and runs well. OMF beadlocked wheels. Located in San Antonio Texas area. I’m motivated to sell and work with shipping options but serious inquiries only interested in a large sport ATV that won’t come around again.
Here’s a photo from a few weeks ago. I can send over more photos, videos, or we can have a FaceTime session to take a look remotely. Let me know.
