This procedure covers the removal and replacement of the steering damper (stabilizer) on a 2015-2020 Ford F-150 with 3.5L EcoBoost V6 engine.

Warnings

Tools required

Parts

• Steering damper assembly × 1 — Use OEM specification or aftermarket equivalent
• Mounting hardware kit (if corroded) × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Place wheel chocks behind rear wheels
3. Raise front of vehicle and support securely on jack stands at frame contact points
4. Allow steering and suspension components to hang at full droop
5. Spray mounting hardware with penetrating oil if corrosion is present

Procedure

1. 1

   Locate steering damper
   Position yourself under the front of the vehicle. The steering damper is mounted horizontally between the frame and the steering linkage on the driver side. It resembles a shock absorber and runs parallel to the tie rod assembly.
2. 2

   Remove damper-to-linkage mounting bolt
   Using an 18mm wrench, remove the bolt securing the steering damper to the tie rod or center link. The damper eye will be attached with a through-bolt and nut. Hold the bolt head while loosening the nut to prevent spinning. Remove the bolt completely and retain any washers or bushings.
3. 3

   Remove damper-to-frame mounting bolt
   Using a 15mm wrench, remove the bolt securing the opposite end of the steering damper to the frame bracket. Support the damper while removing the fastener. Note the orientation of any washers or spacers for reinstallation.
   ⚠The damper may be under slight tension. Support it to prevent it from falling when the bolt is removed.
4. 4

   Remove steering damper
   Lower the steering damper from the vehicle. Inspect both mounting eyes for cracks, elongation, or damage. Check the damper shaft for fluid leaks, scoring, or bending. A failed damper will often show oil seepage around the shaft seal.
5. 5

   Clean mounting points
   Use a wire brush to clean the mounting bolt holes in both the frame bracket and tie rod linkage. Remove any rust, dirt, or debris. Inspect the frame bracket for cracks or damage. Verify that mounting bushings in the new damper are in good condition.
6. 6

   Install new steering damper to frame
   Position the new steering damper with the frame-side mounting eye aligned with the bracket. Insert the mounting bolt through the frame bracket and damper eye, ensuring any spacers or washers are in their original positions. Thread the nut onto the bolt but do not fully tighten yet.
7. 7

   Connect damper to steering linkage
   Align the linkage-side mounting eye with the attachment point on the tie rod or center link. You may need to use a pry bar to align the holes. Insert the through-bolt with washers in the correct orientation. Thread the nut onto the bolt and hand-tighten.
8. 8

   Torque mounting fasteners
   Using a torque wrench, tighten both mounting bolts to 31.0 Nm (23 lb-ft). Torque the frame-side bolt first, then the linkage-side bolt. Verify both fasteners are secure and that the damper can move freely through its range of motion without binding.
   Torque spec

   Mounting Bolts31 Nm (23 lb-ft)
9. 9

   Verify installation
   Manually move the damper through its stroke to ensure smooth operation without binding. Check that all mounting hardware is tight and properly seated. Verify clearance between the damper and surrounding components throughout the steering range.

Reassembly

1. Lower vehicle from jack stands carefully
2. Remove wheel chocks
3. Test steering for smooth operation and proper return to center

Verification

• Start engine and turn steering wheel lock-to-lock while stationary to verify no binding or interference
• Perform a slow-speed test drive to confirm improved steering stability and reduction in steering wheel shimmy
• Verify no unusual noises from steering system during turns
• Re-check all mounting bolt torque after 50-100 miles of driving
