Removal and Installation

1. CAUTION: Suspension fasteners are critical components because they affect performance of vital components and systems and their failure can result in major service expense. New fasteners must be installed with the same component number or an equivalent component if installation is necessary. Do not use a replacement component of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these components. Orientation of the fasteners is also important. Make sure the fasteners are installed in the same direction as they were in when removed.
