LUBRICATION

Do not use more than three (3) pumps of grease in any grease fitting at any one time. Excess grease may cause

grease seals to fail or grease migration into areas that could damage components.

Putting more than three pumps of grease in a grease fitting could damage grease seals and cause premature bear-

ing failure.

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 val-

ues.
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.

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.
