I swapped out the front end on my 175 today. I guess I should have studied the diagrams a bit closer. Seems the bearings are UN-housed, as evidenced by the 'raindrops' of balls falling all over the place. It took a while, but I finally found all of them. I guess I just assumed it was a housed bearing. It should be fun trying to re-assemble everything without them continuously falling out. Another day, another lesson learned.
