Hub Bearing Inspection

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.

• Turn each bearing in the hub back and forth [A] while checking for plays, roughness, or binding.

*If bearing play, roughness, or binding is found, replace the bearing.

• Examine the bearing seal [B] for tears or leakage.

*If the seal is tom or is leaking, replace the bearing

Hub Bearing Lubrication

NOTE

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