CptTripps,
I'm already thinking that I'll be worried about these and was hoping someone with more Subaru knowledge would know if they all end up looking like this, or if it really is something to replace now "while I'm there". I'll figure out if I can just buy parts or if I have to buy complete half-shafts and go from there.

Frank,
A lot of force got me to where I was in the picture, and they wouldn't budge past that. A little bit of searching and i found a ball joint socket for an impact wrench designed for these ball joints. It was cheaper than the big wrench so I'm giving that a try if force is the right answer.
