Maintenance
NOTE: Steering problems must be corrected at once by a
qualified mechanic.
Inspect the steering system:
• Check tie rod ends, drag link ends and kingpins. Joints
and fasteners must be tight. Articulating joints must be
well lubricated.
• Check for installation and spread of cotter pins and
tightness of nuts at both ends of tie rod and drag link.
• Check that pitman arm (steering arm at steering gear)
mounting is tight and locked. Check the power steering
system for leaks or hose chafing. Repair at once.
• Maintain proper power steering fluid level.
• Regularly inspect steering column joint bolts and steering
linkage, particularly for body-to-chassis clearance.
Tightening Steering Intermediate Shaft Joint Bolts
Check the steering intermediate shaft joint bolts for tightness
every 60,000 miles (96,000 km) or annually,
whichever
occurs first. Tighten bolts to torque specified in the Torque
Specification Chart at the end of this section. Do not over
tighten .
