HARDWARE
Periodically, the vehicle should be inspected for loose
fasteners. Fasteners should be tightened in accordance
with the Torque Specifications table (Ref. Fig. 10).
Use care when tightening fasteners and refer to the
Technician’s Repair and Service Manual for specific
torque values.
Generally, three classes of standard hardware and two
classes of metric hardware are used in the vehicle.
Grade 5 hardware can be identified by the three marks
on the hexagonal head and grade 8 hardware is identi-
fied by 6 marks on the head. Metric hardware is marked
on the head with 8.8 or 10.9. Unmarked hardware is
Grade 2.

Unless otherwise noted in text, tighten all hardware in accordance with this chart.
This chart specifies 'lubricated' torque figures. Fasteners that are plated or lubricated when
installed are considered 'wet' and require approximately 80% of the torque required for 'dry' fasteners.
