Replace a front sway bar end link on a 2024 Tesla Model 3 Long Range AWD. Straightforward suspension job; the link connects the sway bar to the strut and commonly fails with clunking noises over bumps.

Warnings

Tools required

Parts

• Front sway bar end link (Model 3 specific, side-specific if applicable) × 1 — OEM Tesla Model 3 front sway bar link or equivalent quality aftermarket

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with the key fob away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
3. Disconnect the 12V (or Li-ion low-voltage) battery. On 2024 Model 3, the low-voltage battery is typically located behind the right rear seat back panel or under the floor depending on production variant — refer to architecture notes and the in-vehicle service mode if available.
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal.
5. If at any point you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
6. Chock the rear wheels.
7. Loosen the front wheel lug nuts ~1/2 turn while the vehicle is still on the ground.
8. Raise the front of the vehicle ONLY at Tesla-designated jack points using a proper puck. Support on jack stands rated for the vehicle weight.
9. Remove the front wheel on the side being serviced.
10. Spray penetrating oil on the upper and lower sway bar link nuts and let it soak for several minutes.

Procedure

1. 1

   Locate the sway bar end link
   With the wheel removed, locate the front sway bar end link. It is a vertical link connecting the front sway bar (running across the subframe) to a tab on the strut assembly. Inspect both the upper (strut-side) and lower (sway-bar-side) ball joint boots for tears.
2. 2

   Loosen the upper sway bar link nut
   Insert an appropriately sized Allen/hex key into the end of the upper ball stud to hold it stationary. Using a wrench on the nut, loosen and remove the upper nut. If the stud spins, apply downward pressure on the link while holding the hex; do not use an impact without holding the stud, as it can shred the internal hex.
   ⚠If the internal hex is rounded, you may need to cut the stud with a reciprocating saw. Protect surrounding components — never cut near orange HV cabling or brake lines.
3. 3

   Loosen the lower sway bar link nut
   Repeat the same procedure on the lower nut where the link attaches to the sway bar. Hold the stud with the Allen key and remove the nut.
4. 4

   Remove the old sway bar link
   Once both nuts are off, separate the link from the strut tab and the sway bar. Inspect the mating surfaces and the sway bar bushings for cracking or excessive movement while you have access.
5. 5

   Compare old and new parts
   Place the old link next to the new one. Confirm overall length, stud orientation, and thread size match exactly. Front sway bar links may be side-specific on some Model 3 variants — confirm correct side before installation.
6. 6

   Install the new sway bar link
   Position the new link with the upper stud through the strut tab and the lower stud through the sway bar eyelet. Hand-thread both nuts to ensure clean engagement — do not cross-thread.
7. 7

   Torque the sway bar link nuts
   Holding each ball stud stationary with an Allen key, torque both the upper and lower nuts to the manufacturer-specified value. Use a calibrated torque wrench — do not rely on impact tools for final torque on suspension fasteners.
   ⚠If the link is a one-piece design with a single shaft torque spec rather than per-nut, refer to the Sway Bar Link spec instead. Do not over-torque — ball joints are easy to damage.
   Torque spec

   Sway Bar Link61 Nm (45 lb-ft)
8. 8

   Inspect surrounding suspension
   While access is open, visually inspect the strut, control arm bushings, ball joint boot, sway bar bushings/brackets, and brake hose routing. Note any other items needing service.

Reassembly

1. Reinstall the front wheel. Hand-thread all lug nuts to avoid cross-threading the aluminum hub face.
2. Snug the lug nuts in a star pattern.
3. Lower the vehicle to the ground.
4. Final-torque the wheel lug nuts in a star pattern to spec.
5. Reconnect the 12V/Li-ion low-voltage battery.
6. Close all doors and allow the vehicle to wake. Verify no suspension or stability control warnings on the center display.

Verification

• With the vehicle on the ground, push down firmly on the front fender on the serviced side — there should be no clunking, knocking, or metallic ticking from the sway bar area.
• Test drive over a speed bump or uneven pavement at low speed and listen for clunks. A properly installed link is silent.
• After the test drive, re-inspect both nuts for proper seating and re-verify torque on the lug nuts (Tesla wheels can settle on first drive).
• Check the center display for any chassis, ABS, or stability-control alerts.
• While the vehicle is up to date on this repair, note Tesla's other interval-based services that are NOT 'lifetime': brake fluid every 2 years, cabin air filter every 2 years, drive unit gear oil at the recommended Tesla interval (initial ~12,500 mi then 25–50k mi), and battery coolant inspection at 4 years / 50,000 mi. Tire rotation every ~6,250 mi is also strongly recommended due to instant torque and curb weight.
