I'm not sure what's going on but there is no bosses that I can see. I jacked the car up and moved the front tires like I was turning and the spindle turns and the cone and collar stay straight like it should. I'm not even sure what the purpose for those two bolts are. when I turn the cone and collar the cone, front collar and lower outer case turn but you can only go to about 2 o'clock (and still no bosses.) That bolt in pic in upper left, when I un screwed the bolt I didn't move anything and just tried to put it back with in a minute so that's why its a bit funny. Maybe its for a column shift car. mines a floor console???
