Relay Rod Replacement Without FH4

Tools Required

J 26813-B Steering Linkage Puller

Important: A non-adjustable relay rod connects the pitman arm to the steering arm. If the relay rod becomes worn or damaged, replace the complete assembly.

1. Remove the cotter pin (4).
2. Discard the cotter pin.
3. Remove the relay rod/pitman arm nut (3).



4. Use the J 26813-B in order to remove the relay rod from the pitman arm



5. Remove the cotter pin (3).
6. Remove the nut (4).
7. Use the J 26813-B in order to remove the relay rod from the steering arm.



8. Inspect the relay rod (10) for damage
9. Inspect the end assembly stud threads for damage.
10. Inspect the assembly rubber seals for the following conditions:

•

Damage

•	Deterioration

11. Install the nuts (9,12).
12. Use a torque wrench in order to measure the torque used to turn the ball stud.
13. Replace the relay rod if the turning torque is less than 0.5 N·m (5 lb in).

1. Install the relay (2) ball joint-pitman arm end to the pitman arm (1).
2. Install the pitman arm/relay rod nut (3).



3. Install the relay rod (1) ball joint steering arm end to the steering arm.

Important: Do not back off a relay rod nut in order to insert a cotter pin.

5. Advance both relay rod nuts (9,12) to the nearest cotter pin slot.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

6. Tighten both relay rod ball joint nuts.

Tighten
Tighten both relay rod nuts to 160 N·m (120 lb ft).

7. Install new cotter pins
8. Lubricate the relay rod with chassis lubricant. Refer to Fluid and Lubricant Recommendations and Maintenance Schedule in Maintenance and Lubrication.
