Showa 16172-0557 rebuild?

So I was climbing a hill today and smacked a root pretty hard. Blew the side wall out of the tire but that's the least of my worries. I have a 2021 Kawasaki teryx4 le and I'm pretty sure I broke some teeth in the power steering. When the wheel is centered the wheels are not and it binds up turning left. The steering arms are fine and the shaft and knuckle are good leading into the eps looks good. I guess my question is, is there a way to rebuild this thing because it is a ridiculously expensive part.
