This procedure covers removal and replacement of the front lower control arm bushings on a 2011-2014 Ford F-150 3.5L EcoBoost 4WD, requiring separation of the ball joint and removal of the control arm.
Warnings
⚠️Never work under a vehicle supported only by a jack. Always use properly rated jack stands on solid, level ground.
⚠Control arm bolts must be torqued with vehicle weight on the suspension. Failure to do so will cause premature bushing failure.
⚠Ball joint separators can generate sudden release of tension. Keep hands and face clear of the separation point.

Parts
- Front lower control arm bushing kit × 2 — Use OEM specification or Moog K200869
- Cotter pin × 2 — Use OEM specification
Preparation
- Park vehicle on level, solid surface and engage parking brake
- Place wheel chocks behind rear wheels
- Loosen front wheel lug nuts while vehicle is on ground (do not remove)
- Raise front of vehicle and support securely on jack stands placed on frame rails
- Remove front wheels completely
- Spray all fasteners with penetrating oil and allow to soak for 10-15 minutes
Procedure
- 1Remove cotter pin and loosen ball joint nutLocate the lower ball joint nut at the bottom of the steering knuckle. Remove the cotter pin using pliers or a cotter pin remover. Using a 21mm socket, loosen the ball joint nut but do not remove it completely yet. Leave it threaded on 2-3 turns to protect the threads during separation.
- 2Separate ball joint from knucklePosition a ball joint separator tool between the lower control arm and the steering knuckle at the ball joint taper. Strike the separator firmly with a hammer or tighten the screw-type separator until the ball joint releases from the knuckle taper. Once separated, remove the ball joint nut completely. Support the knuckle assembly to prevent it from hanging on the brake hose or CV axle.⚠The ball joint will release suddenly. Ensure the knuckle is supported and keep hands clear of pinch points.
- 3Disconnect sway bar link (if necessary)If the sway bar link interferes with control arm removal, disconnect it from the lower control arm. Hold the link shaft with an Allen key (typically 6mm) and remove the nut using an 18mm socket. Allow the link to hang from the sway bar.Torque specSway Bar Link Nuts55 Nm (41 lb-ft)
- 4Mark control arm position and remove mounting boltsBefore removal, mark the position of the control arm relative to the frame mounting points using a paint marker or scribe. This helps with alignment during reinstallation. Using a 21mm socket and breaker bar, remove the front and rear control arm mounting bolts. Support the control arm as you remove the final bolt, as it will drop free.⚠Control arm is heavy and may drop suddenly when final bolt is removed. Keep hands and feet clear.
- 5Remove control arm from vehicleLower the control arm and remove it from the vehicle. Maneuver it carefully around the CV axle, brake components, and frame. Place the control arm on a stable work surface for bushing removal.
- 6Press out old bushingsClean the control arm bushing bores with a wire brush. Using a hydraulic press with appropriately sized adapters or a bushing removal tool, press out the old bushings from the control arm. The bushings are press-fit and will require significant force. Ensure the control arm is properly supported in the press to avoid damage. Press from the inside out to avoid damaging the bore.⚠Use proper press adapters that contact only the bushing, not the control arm bore. Misalignment can damage the arm.
- 7Clean bushing bores and inspect control armThoroughly clean the bushing bores in the control arm using a wire brush and solvent. Remove all rust, debris, and old rubber. Inspect the control arm for cracks, bends, or damage. Check the ball joint for excessive play or torn boots. Replace the entire control arm if any damage is found.
- 8Press in new bushingsApply a light coat of soapy water or bushing installation lubricant to the outside of the new bushings and the control arm bores. Align the bushing carefully with the bore, ensuring it is perfectly square. Using the hydraulic press with proper adapters, press the bushing straight into the bore until it is fully seated and flush with the control arm. The bushing orientation voids should align with the control arm mounting bolt axis. Repeat for all bushings.⚠Bushings must be pressed in straight and square. Cocking will damage both bushing and control arm. Use proper size adapters.
- 9Reinstall control arm to framePosition the control arm with new bushings back into the vehicle, maneuvering around the CV axle and suspension components. Align the control arm with the frame mounting points using your earlier reference marks. Insert both front and rear mounting bolts and thread them by hand. Do NOT torque these bolts yet - they must be torqued with vehicle weight on the suspension.
- 10Reconnect ball joint to knuckleRaise the lower control arm using a floor jack to align the ball joint stud with the hole in the steering knuckle. Insert the ball joint stud into the knuckle and install the ball joint nut. Tighten the nut to specification using a 21mm socket and torque wrench. Install a new cotter pin through the castellated nut and ball joint stud, bending the ends to secure.ℹ️If cotter pin holes do not align, tighten nut further until next slot aligns. Never loosen to align.Torque specBall Joint Nut101 Nm (75 lb-ft)
- 11Reconnect sway bar linkIf previously disconnected, reconnect the sway bar end link to the lower control arm. Hold the link shaft with an Allen key and tighten the nut to specification using an 18mm socket and torque wrench.Torque specSway Bar Link Nuts55 Nm (41 lb-ft)
- 12Reinstall wheels and lower vehicleReinstall the front wheels and hand-tighten the lug nuts in a star pattern. Lower the vehicle carefully from the jack stands until the full weight of the vehicle is resting on the suspension, but keep the jack stands in place as a safety backup.
- 13Torque control arm bolts with vehicle weight on suspensionWith the vehicle weight fully on the suspension (wheels on ground or on stands at normal ride height), torque the front and rear control arm mounting bolts to specification using a 21mm socket and torque wrench. This is critical - torquing these bolts with the suspension hanging will cause premature bushing failure.⚠Control arm bolts MUST be torqued at normal ride height with vehicle weight on suspension. This is critical for bushing longevity.Torque specControl Arm Bolts165 Nm (122 lb-ft)
- 14Final torque wheel lug nutsRemove jack stands completely and lower vehicle fully to the ground. Torque all wheel lug nuts to specification in a star pattern using a 19mm socket and torque wrench.Torque specWheel Lug Nuts156 Nm (115 lb-ft)
Reassembly
- Repeat all steps for the opposite side if replacing both control arm bushings
- Double-check that all fasteners are tightened to specification
- Verify new cotter pins are properly installed and bent
- Ensure no tools or parts were left in the wheel well or under the vehicle
Verification
- Test drive the vehicle at low speed in a safe area and verify no unusual noises from the front suspension
- Check for proper steering response and no pulling to either side
- Perform a visual inspection under the vehicle to confirm no fluid leaks and all fasteners are secure
- Schedule a professional front-end alignment within 50 miles of completion, as control arm removal affects alignment settings
