Parts
- Front sway bar link (left) × 1 — Use OEM specification
- Front sway bar link (right) × 1 — Use OEM specification
Preparation
- Park vehicle on level 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 with floor jack at manufacturer-designated lift points
- Support vehicle securely on jack stands under frame rails
- Remove front wheels completely
Procedure
- 1Access the sway bar linkLocate the sway bar link connecting the lower control arm to the sway bar. The link is a vertical rod with ball joints at both ends. Inspect the area for corrosion or damage.
- 2Apply penetrating lubricantSpray penetrating lubricant on both upper and lower sway bar link nuts. Allow 5-10 minutes to penetrate if hardware shows corrosion. This step is optional but recommended for easier removal.
- 3Remove upper sway bar link nutInsert a 6mm Allen key into the top of the sway bar link shaft to hold it stationary. Using an 18mm wrench, loosen and remove the upper nut that attaches the link to the sway bar. If the ball joint stud spins, hold the shaft firmly with the Allen key.
- 4Remove lower sway bar link nutInsert the 6mm Allen key into the bottom of the sway bar link shaft. Using an 18mm wrench, loosen and remove the lower nut that attaches the link to the lower control arm. Hold the shaft with the Allen key to prevent spinning.
- 5Remove sway bar linkPull the sway bar link downward to disengage the upper ball stud from the sway bar, then remove the link completely from the vehicle. Inspect the sway bar and control arm mounting points for damage or wear.
- 6Install new sway bar linkPosition the new sway bar link with the upper ball stud inserted into the sway bar mounting hole and the lower ball stud into the lower control arm hole. Ensure both studs are fully seated in their respective mounting points.
- 7Install and torque lower nutThread the lower nut onto the ball stud by hand until snug. Insert the 6mm Allen key into the shaft and hold firmly. Torque the lower nut to specification using a torque wrench and 18mm socket.Torque specSway Bar Link71 Nm (52 lb-ft)
- 8Install and torque upper nutThread the upper nut onto the ball stud by hand until snug. Insert the 6mm Allen key into the shaft and hold firmly. Torque the upper nut to specification using a torque wrench and 18mm socket.Torque specSway Bar Link71 Nm (52 lb-ft)
- 9Repeat for opposite sideIf replacing both sway bar links, repeat steps 1 through 8 for the opposite side of the vehicle. Both links should be replaced as a pair for balanced suspension performance.
- 10Reinstall wheelsPosition the wheel onto the hub and thread all lug nuts by hand. Tighten lug nuts in a star pattern until snug but do not fully torque yet.
- 11Lower vehicle and final torqueRemove jack stands and carefully lower the vehicle to the ground. With the vehicle's full weight on the wheels, torque the wheel lug nuts to specification in a star pattern.Torque specWheel Lug Nuts156 Nm (115 lb-ft)
Reassembly
- Ensure all fasteners are properly torqued to specification
- Verify sway bar link ball studs are fully seated in mounting points
- Check that no tools or parts were left in the wheel well area
Verification
- Test drive the vehicle at low speed and listen for any clunking or rattling noises from the front suspension
- Turn the steering wheel lock-to-lock while moving slowly to verify proper sway bar operation
- Perform a visual inspection under the vehicle to confirm all fasteners are secure
- Check for any unusual handling characteristics or pulling to one side
