Start by removing the rear wheel and any other components that might be in the way of the shock linkage. Then, unbolt the shock linkage from the frame and swingarm. Use the good bearings puller to remove the old bearings from the linkage plates. Be careful not to damage the plates or the bearings themselves.

Yes, the rear axle should have a sleeve/spacer inside the hub between the wheel bearings. The sleeve/spacer helps to prevent the bearing inner races from being pushed inwards when the axle is tightened. The sleeve/spacer is not always included with the wheel bearings, so you may need to purchase it separately. The size of the sleeve/spacer will vary depending on the make and model of your motorcycle.

Yes, it is normal for crankshaft bearings to be rubber sealed. The rubber seal helps to prevent dirt and contaminants from entering the bearing and causing premature wear. Rubber sealed crankshaft bearings are a relatively new development, and they are not yet as common as traditional non-sealed bearings. However, they are becoming increasingly popular, as they offer a number of advantages over non-sealed bearings.
