I knew the deal was too good to be true but I hope there may still be something there to salvage

Anyway I'm trying to set my expectations for pricing on a) bearing replacement and b) full spindle replacement
Hopefully someone can comment their experience and pricing so I can see if I'm still getting a deal or a money pit.

This model has the base 7k rpm spindle and through tool coolant.

This is a side gig so this machine may only see 500 hours of use a year. I just need more capacity than my Centroid knee mill provides and this older Okuma seemed to fit the bill at first glance. I see these machines going for $25k-$35k and this one was priced at a little less than half because it needs to move this week.
