NOTICE:
Suspension fasteners are critical parts that affect the
performance of vital components and systems. Failure of these fasteners
may result in major service expense. Use the same or equivalent parts if
replacement is necessary. Do not use a replacement part of lesser
quality or substitute design. Tighten fasteners as specified.
