General Information
WARNING
To prevent property damage, personal injury,
and / or death, always follow recommended
procedures for steering system maintenance.
Maintain the steering system in proper condition;
otherwise, reduced steering ability could result.
Have a technician examine the steering mechanism. Minor
adjustments could head off further problems.
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 system for leaks or hose chafing.
Maintain proper power steering fluid levels.
Regularly inspect steering column joint bolts and steering
linkage, particularly for body-to-chassis clearance.
NOTE: Have any steering problems corrected at once by a
qualified service technician.
Tightening Steering Intermediate Shaft Joint Bolts
As a good maintenance practice, it is recommended that
steering intermediate shaft joint bolts be checked for tightness
every 120,000 miles (193,000 km) or annually, whichever occurs
first.
Lubrication Points
The steering shaft is lubricated at the three points shown in
the illustration above.
