Read all of manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notes, Cautions and Warnings
HARDWARE
Periodically, the vehicle should be inspected for loose
fasteners. Fasteners should be tightened in accordance
with the Torque Specifications table (Ref. Fig. 25 on page
19).
Use care when tightening fasteners and refer to the
Technician’s Repair and Service Manual for specific
torque values.
Generally, three grades of hardware are used in the vehi-
cle. Grade 5 hardware can be identified by the three
marks on the hexagonal head and grade 8 hardware is
identified by 6 marks on the head. Unmarked hardware is
Grade 2 (Ref. Fig. 25 on page 19).

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.
