Thanks everyone for your thoughts and insights as well.

Pretty sure you just need to replace the main shaft and bearings (part 8M0050018, about $60-$75) seals (26-8M200165, 26-862040 about 10 bucks), and tolerance ring (862039) and of course a standard rebuild (47-862232A2 about 35 bucks) while you have it out. You can verify these part numbers at your dealer with your engine serial number. There's no need to drop $700+ for an entire pump if just the bearings failed.
There's a good write-up on the standard rebuild, with a great drawing of all the parts in the pump right here:

I'm a big fan of fixing things and only replacing parts that are actually failed. It's amazing how much information is available on the web for people like me. In just the past year, using nothing more than the internet and good tools, I have been able to repair: a 50" plasma TV (failed Z sustain and power supply, $130 in parts), A Nikon AF lens (failed FPC focusing sensor, $26) a mercruiser starter (failed ring gear, $7), a Coleman 5000 watt generator (worn out Tecumseh 10HP engine, $100 for a brand-new short block assembly), a garage door opener (failed plastic gear, $5) and a boat trailer axle (spindle, backing plate assembly and brake drum assembly, $150). I'm sure there's other stuff, this is just what comes to mind.
