NOTE: Suspension and subframe fasteners are critical parts because they affect performance of vital parts and systems and their failure may result in major service expense. A new part with the same part number must be installed if installation becomes necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.
