Thanks for the input. Yeah they're not out to gouge customers. It's tough being a little import dealer in a hardcore "USA all the way" area. I think they want to keep it limited to actual needed repairs at a realistic cost to help the image of Subaru overall. This approach has paid off big time, the dealership recently got a major overhaul compliments of SOA because of sales.
The Toyota dealer in the area does not think this approach is necessary.
Semi-non update: When I was under the car checking the diff/axles I noticed that the left rear tire is worn on the inside. It got this way (mostly) up on the front right, but was rotated to the left rear a few months ago (Sam's Club, they also re-balanced). The tires are BFGoodrich Touring T/A's, not a sticky noisy tire, actually quite hard. 6 to 7/32's left everywhere else. Could it be the tire?
