Hub Bearing

Hub Bearing Inspection

Since the hub bearings are made to extremely close tol­erances, the clearance cannot normally be measured.

NOTE

О 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 torn or is leaking, replace the bearing.

Hub Bearing Lubrication

• Clean and grease the rear left side hub bearing in accor­ dance with the Periodic Maintenance chapter.

NOTE

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