STEERING LINKAGE
The steering linkage consists of the pitman arm, drag link, tie rod, tie rod arms, and steering arms. Refer
to Meritor Maintenance Manual No. 23- Bus and Coach Front Axles , supplied with the coach. Always
use the most up-to-date documentation for tie rod and steering arm inspection and repair information.
Keep in mind that many steering box and power steering components are covered in the Hydraulic
System chapter of this manual; be prepared to refer frequently to that chapter while working on steering
assemblies.
Maintenance Suggestions
• Never high-pressure wash or steam-clean the power steering gear, as this can force contaminants
inside the gear.
• Make sure vehicle wheel cut or clearances meet specifications, and that pitman arm timing marks
are aligned properly to prevent internal bottoming of the steering gear.
• Keep tires inflated to correct pressure.
• Never use a torch to remove the pitman arm.
• Investigate and immediately correct the cause of any play, rattle, or shimmy in any part of the
steering system.
• Make sure the steering column is properly aligned.
Steering Lubrication
All lubrication fittings must be clean before applying lubri -
cant. Ensure the equipment used in applying the lubricant is
clean. Every precaution should be taken to prevent entry of
dirt, grit, lint, or other foreign matter into lubricant contain-
ers. Replace fittings which have become worn or damaged.
Refer to the Preventive Maintenance chapter for recom-
mended lubrication intervals. More frequent intervals may
be applied under severe operating conditions. Refer to
the Specifications chapter for recommended greases and
lubricants.
1. Tie rod ends. Lubricate the fitting at each tie rod
end until new grease comes out from the boot.
2. Drag link ends. Lubricate the fitting at both drag
link ends until new grease comes out.
3. Spindle. Lubricate the fitting each at the top and
bottom of the left and right kingpins until new
grease comes out of the thrust bearing seal and
the upper shim pack.
4. Steering column U-joints. Lubricate the fitting
at each yoke and at the slip joint.
