Since the hub bearings are made to extremely close tolerances, the clearance can not normally be measured.
NOTE
Do not remove any bearings for inspection. If any bearings are removed, they will need to be replaced with new ones.
If bearing play, roughness or binding is found, replace the bearing.
If the seal is torn or is leaking, replace the bearing.

Hub Bearing Lubrication
NOTE
Since the hub bearings are packed with grease and sealed, lubrication is not required.
