This procedure covers the removal and replacement of the pitman arm on a 2011-2014 Ford F-150 with 5.0L V8 4WD, including disconnecting the steering linkage and using a specialized puller tool.

Warnings

Tools required

Parts

• Pitman arm × 1 — Motorcraft or equivalent - verify spline count and length
• Pitman arm nut (castle nut) × 1 — Use OEM specification
• Cotter pin × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and apply parking brake
2. Place wheel chocks behind rear wheels
3. Center the steering wheel and mark its position with tape
4. Raise front of vehicle with floor jack and support securely on jack stands at frame rails
5. Remove front wheels
6. Spray pitman arm nut and center link connection with penetrating oil and allow to soak for 10-15 minutes

Procedure

1. 1

   Access the pitman arm
   From underneath the vehicle, locate the pitman arm extending from the steering box on the driver side frame rail. The pitman arm connects the steering box output shaft to the center link of the steering linkage. Clean the area around the connections with a wire brush to remove dirt and debris.
2. 2

   Remove cotter pin and castle nut
   At the connection between the pitman arm and center link (drag link), straighten and remove the cotter pin. Use a socket and breaker bar to remove the castle nut securing the pitman arm ball stud to the center link. Do not reuse the cotter pin.

3. 3

   Separate pitman arm from center link
   Using a pitman arm puller or pickle fork, separate the pitman arm ball stud from the center link. Position the puller properly on the center link and tighten to apply pressure until the taper releases. Do not strike the assembly with a hammer as this can damage components.
   ⚠The ball stud may release suddenly under pressure. Keep hands and fingers clear of pinch points.
4. 4

   Mark pitman arm orientation
   Before removing the pitman arm from the steering box sector shaft, mark the position of the pitman arm relative to the sector shaft using a paint pen or scribe. This ensures correct reinstallation to maintain steering geometry. Note the position of any alignment marks already present.
5. 5

   Remove pitman arm retaining nut
   Using a socket and breaker bar, remove the large nut securing the pitman arm to the steering box sector shaft. This nut requires significant force to remove. Hold the pitman arm steady to prevent turning the steering box output shaft.

6. 6

   Remove pitman arm from sector shaft
   Install a pitman arm puller onto the pitman arm, positioning the center screw against the end of the sector shaft and the puller arms behind the pitman arm. Tighten the puller screw gradually and evenly. The arm will release from the tapered shaft as pressure is applied. Do not use heat or strike the arm with a hammer.
   ⚠The pitman arm is interference-fit on a tapered shaft and may release suddenly. Ensure the puller is properly positioned to prevent the arm from falling.
7. 7

   Clean sector shaft and inspect
   Once the pitman arm is removed, clean the steering box sector shaft with a wire brush and inspect for damage, scoring, or wear. The taper should be smooth and free of damage. Inspect the splines inside the removed pitman arm for wear or damage. Clean the ball stud taper on the new pitman arm.
8. 8

   Install new pitman arm onto sector shaft
   Apply a light coat of white grease or anti-seize to the sector shaft splines (not the taper). Align the new pitman arm with the orientation marks made during removal and slide onto the sector shaft, ensuring the splines engage properly and the arm is oriented correctly. The arm should slide on partway by hand.
9. 9

   Install and torque pitman arm nut
   Thread the pitman arm nut onto the sector shaft and tighten by hand. Using a torque wrench, tighten the nut to specification. This will draw the pitman arm fully onto the tapered shaft. Verify the pitman arm is fully seated and aligned with reference marks.

10. 10

    Connect pitman arm to center link
    Position the pitman arm ball stud into the center link socket. Install the castle nut and tighten to specification using a torque wrench. Align the castle nut slots with the hole in the ball stud by tightening (never loosen to align). Install a new cotter pin and bend the legs to secure.
    ⚠If castle nut slots do not align with the cotter pin hole, tighten the nut further until alignment is achieved. Never loosen the nut to align.

    Reinstall wheels
    Reinstall the front wheels, threading lug nuts by hand initially. Lower the vehicle until the tires contact the ground but are not fully weighted. Torque the lug nuts to specification in a star pattern. Fully lower the vehicle and remove jack stands.

Reassembly

1. Verify steering wheel is still centered and pitman arm orientation matches reference marks
2. Check all connections are tight and cotter pin is properly installed
3. Start engine and turn steering wheel lock-to-lock to verify proper operation and no binding

Verification

• With engine running, turn steering wheel fully left and right to verify smooth operation with no binding, popping, or unusual noises
• Check for any fluid leaks at the steering box where the sector shaft exits
• Verify steering wheel returns to center position when released
• Test drive vehicle at low speed in a safe area to confirm steering response is normal
• Schedule a professional front-end alignment to ensure proper steering geometry and prevent tire wear
