Sorry for the delay, I've been out of town. I did a quick search on Kubota B2910 factory shop manual, and came up with this URL.....

It looks like these things are getting kind of pricey, but I'm glad I have mine....has saved me a couple of trips to the dealer.
Sorry for your troubles.
I basically dis-assembled mine in the field, took the hub to the dealer and had them pull it apart for me. Reassembled in the field, total cost was just under 300.00. I think. Needed special fluid for axle, and that gasket sealer.
Did not replace other side, will wait until it snaps too.
