Steering System
WARNING: Failure to maintain the steering system in proper
condition can cause reduced steering ability resulting in property
damage, personal injury or death.
Note: Have any steering problems immediately corrected by a qualified
service technician.
Ask your service technician to examine the steering mechanism. Only
minor adjustments may be necessary. Regular inspections should include:
• Checking the tie rod, drag link end clamp bolts and ball joints for
proper tightness.
• Checking for installation and spread of cotter pins and tightness of
nuts at both ends of the tie rod and drag link.
• Checking that the pitman arm (steering arm at steering gear)
mounting is tight and locked. Check system for leaks or hose chafing.
Repair immediately, if necessary.
• Maintaining proper steering gear and power steering pump lubricant
levels.
• Checking steering column joint bolts and steering linkage, particularly
for body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, check steering column joint bolt
tightness every 60000 miles (96000 kilometers) or annually, whichever
occurs first. Do not overtighten the bolts.
Hydraulic System
Whenever draining and refilling the power steering's hydraulic system for
any reason, bleed air from the system before returning the vehicle to
service. Failure to bleed the hydraulic system properly can result in
degradation of power system performance.
Consult an authorized dealer who is aware of the proper procedures for
filling and bleeding the system.
Catalytic Converter (Diesel Engine)
Note: If your vehicle is equipped with a catalytic converter or muffler,
do not blend waste oil with diesel fuel. Operate only on ultra-low sulfur
(less than 15 parts per million sulfur) diesel fuel with a cetane value of
45 or higher.
