Bearing, inboard, front hub, Wraith

Before assembly it is important that the hub bearings are packed with a good quality high melting point grease. This should be worked in to the bearing cage around the balls or rollers. The bearing must not be packed fully with grease, as this may prevent the cage from moving or the balls from rotating freely. Premature bearing failure may result. It is recommended that about half the available space within a bearing should be packed with grease.

The space between the two bearings should be filled one third to a half full of grease.
