This procedure covers the removal and replacement of the front sway bar (stabilizer bar) on a 2021-2024 Ford F-150 with 3.5L EcoBoost engine, including disconnecting the sway bar links and removing the frame-mounted brackets.

Warnings

Tools required

Parts

• Front sway bar × 1 — Use OEM specification
• Sway bar bushings (if deteriorated) × 2 — Use OEM specification
• Sway bar links (if worn) × 2 — Use OEM specification

Preparation

1. Park vehicle on level, solid surface and engage parking brake
2. Loosen front wheel lug nuts while vehicle is on ground (do not remove)
3. Raise front of vehicle using floor jack at designated lift points
4. Support vehicle securely with jack stands under frame rails rated for vehicle weight
5. Remove both front wheels completely
6. Spray penetrating oil on sway bar link nuts and bracket bolts if corrosion is present

Procedure

1. 1

   Disconnect driver side sway bar link
   Locate the sway bar link connecting the sway bar to the lower control arm on the driver side. Insert a 6mm Allen key into the shaft of the link stud from the top to prevent rotation. Using an 18mm socket, remove the lower nut securing the link to the control arm. The link may remain attached to the sway bar for now.

2. 2

   Disconnect passenger side sway bar link
   Repeat the process on the passenger side. Insert a 6mm Allen key into the link stud shaft to hold it stationary, then remove the lower nut with an 18mm socket. Both links should now be disconnected from the lower control arms.

3. 3

   Support the sway bar
   Position a floor jack or support under the center of the sway bar to prevent it from dropping suddenly when the brackets are removed. Raise jack just enough to contact the bar without applying pressure.
4. 4

   Remove driver side sway bar bracket
   Locate the sway bar mounting bracket on the driver side frame rail. Using a 15mm socket, remove both bolts securing the bracket to the frame. Remove the bracket and note the orientation of the rubber bushing. Keep brackets and hardware organized for reinstallation.

5. 5

   Remove passenger side sway bar bracket
   Using a 15mm socket, remove both bolts securing the passenger side bracket to the frame rail. Remove the bracket and bushing. The sway bar should now be free from the frame mounts.

6. 6

   Remove sway bar from vehicle
   Lower the support jack slowly while guiding the sway bar. Maneuver the bar downward and toward one side to clear the frame and suspension components. The sway bar links may still be attached at the top - slide them off the sway bar ends as you remove it. Extract the sway bar from underneath the vehicle.
   ⚠Sway bar is heavy and awkward. Use caution when maneuvering it out from under the vehicle to avoid injury or damage to brake lines and other components.
7. 7

   Inspect bushings and links
   Examine the rubber bushings removed with the brackets for cracking, tearing, or excessive wear. Check sway bar links for torn boots, loose ball joints, or binding. Replace any worn components. Clean the sway bar where bushings mount using a wire brush to remove dirt and corrosion.
8. 8

   Install new or cleaned sway bar
   If installing a new sway bar, ensure it matches the original configuration. Position the sway bar up into the vehicle, routing it through the suspension and aligning the ends where the links attach. Orient the bar so the bushing mounting areas align with the frame bracket locations. Use the support jack to hold the bar in approximate position.
9. 9

   Install sway bar bushings and brackets
   Install the rubber bushings onto the sway bar in the correct orientation (split side facing rearward). Position the mounting brackets over the bushings and align with the frame rail holes. Install bracket bolts finger-tight on both sides but do not torque yet. Ensure bushings are properly seated and centered in brackets.

10. 10

    Torque sway bar bracket bolts
    Once both brackets are installed and properly aligned, torque all four bracket bolts (two per side) to specification using a 15mm socket and torque wrench. Torque in a criss-cross pattern to ensure even clamping pressure on the bushings.

11. 11

    Connect sway bar links
    Align the sway bar link studs with the holes in the sway bar ends and lower control arms. You may need to use a pry bar or jack to align the suspension geometry. Install the lower nuts on both links finger-tight first. Insert a 6mm Allen key into each link stud from the top to prevent rotation, then torque the lower nuts to specification using an 18mm socket.

    Reinstall wheels
    Install both front wheels, threading lug nuts by hand initially to avoid cross-threading. Tighten lug nuts in a star pattern with a hand wrench but do not fully torque yet.

    Lower vehicle and final torque
    Remove jack stands and carefully lower the vehicle to the ground. With the vehicle weight on the wheels, torque the wheel lug nuts to specification in a star pattern using a torque wrench and 19mm socket.

Reassembly

1. Ensure all fasteners are torqued to specification per the procedure steps
2. Verify sway bar bushings are properly seated in brackets and not pinched or twisted
3. Confirm sway bar links move freely without binding or excessive play
4. Check that no brake lines, wiring, or other components are in contact with the sway bar

Verification

• Test drive vehicle at low speed and verify no unusual noises from front suspension
• Turn steering wheel lock-to-lock while stationary and listen for clunking or binding
• Drive over bumps and verify sway bar is functioning properly with no rattles or knocking sounds
• Perform visual inspection underneath vehicle after test drive to confirm all fasteners remain tight and properly installed
