HARDWARE
Periodically the vehicle should be inspected for loose fas-
teners. Fasteners should be tightened in accordance with
the Torque Specifications table (Ref Fig. 6).
Use care when tightening fasteners and refer to the Tech-
nician’s Repair and Service Manual for specific torque
values.
Generally, two grades of hardware are used in the
vehicle.
• Grade 5 hardware can be identified by the three
marks on the hexagonal head.
• 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.
