Inspect and clean
Wipe the bearings, hub, and cones free of grease and dirt. Inspect the parts for cracks or defects.

Repeat the process of cleaning and greasing the bearings on the opposite side of the hub.
Reassemble the hub by reversing the process of taking it apart. Adjust the distance of the cones from the hub to make it fit securely.
