Well I can answer my own question. I'm in big trouble.
The whole bearing in the rear that held the back end of the PTO shaft is gone. Where it all went and the damage it caused is subject to lots of speculation. Dealer says 4-6k is their estimate, could be lower but they wont know until they inspect the gears and there is the question if metal got into the HST. I pick up the shop manuel on Friday and will speak to the mechanics. I don't think I have a choice but to do the work myself. I might have them help me inspect the parts for damage. They seem willing to help me through the work myself.
First order of business to to dissect the HST oil filter and see what it picked up.
Parts in canada seem about 25% higher even though our dollar is higher so I may be getting may parts from the US.
