HARDWARE
Periodically, the vehicle should be inspected for loose fasteners. Fasteners should be tightened in accordance with the Torque
Specifications table.
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 identified by 6 marks on the head. Metric
hardware is marked on the head with 8.8 or 10.9. Unmarked hardware is Grade 2.
ALL TORQUE FIGURES ARE IN FT. LBS. (Nm)

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.
