Installation Procedure

Important: 

   • Make sure that all of the parts are clean and free of grease.
   • Apply an approved high-temperature front wheel bearing grease to the spindle at the inner and outer bearing seat, the shoulder, and the seal seat.
   • Also, finger apply a small amount of grease inboard of each bearing cup in the hub/rotor.
   • Pressure pack the bearings with a grease machine, or hand pack the bearings. Make sure the grease is worked thoroughly into the rollers, the cone, and the cage.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
