Having no success finding a parts manual that looks anything like this wheel. I've attached a video below to show you the layout of all the hardware on the axle. When I tighten down the brake-side axle nut, the wheel starts to lock up. I think it is the brake carrier being pushed into the shim on the other side, not the bearings themselves, but I'm not entirely sure. Would appreciate any guidance, my hope is that I'm just missing a washer or a nut somewhere. If the brake-side axle nut is just finger tight, the wheel spins well enough. Wrench tightened, different story.
