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.

When tightening the nut a minimum torque of 50 N·m (37 lb ft) must be obtained. If 50 N·m (37 lb ft) is not obtained, inspect the nut for stripped threads. If the threads are satisfactory, replace the ball joint and knuckle. If required, turn the nut up to an additional 60 degrees in order to allow for the installation of the cotter pin.
