The two Items 32 are the wheel bearings. Item 33 is the front hub. 34 is the collar that holds the wheel bearings on the stub axle. 35 is the grub screw that holds the collar on the stub axle. So, you loosen the grub screw with an Allen key, then slide off the collar. If the stub axle is rusty, you'll need to use some penetrating fluid and let it soak for a while first. Then you can slide the hub off the stub axle, with the wheel bearings still inside the hub. Once the hub is off, you pull the bearings out of it, using more penetrating fluid.
