Sway Bar Link - Rear

Replace a rear sway bar (stabilizer) end link on a 2024 Tesla Cybertruck Cyberbeast. The procedure is straightforward but requires care due to the truck's mass, air suspension, and 48V low-voltage architecture.

Warnings

Tools required

Parts

• Rear sway bar end link assembly (manufacturer-specified for Cybertruck) × 1 — Tesla Cybertruck rear stabilizer link — refer to Tesla EPC for current part number

Preparation

1. Park on level ground, place in P, and engage the 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. Before disconnecting power, enter the touchscreen Service Menu and place the air suspension in Jack Mode (or equivalent transport/service mode) to prevent self-leveling.
4. Disconnect the 48V low-voltage battery per Tesla's published procedure for Cybertruck. Note: this is a 48V system, not 12V — use appropriate procedure and PPE.
5. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal.
6. 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.
7. Chock the front wheels.
8. Loosen the rear wheel lug nuts on the affected side while the tire is still on the ground.
9. Lift the rear of the vehicle at the manufacturer-specified jacking points using rated equipment, and support on jack stands. The Cybertruck is heavy — verify jack/stand ratings.
10. Remove the rear wheel on the affected side.

Procedure

1. 1

   Inspect the work area
   Visually inspect the rear sway bar, end link, lower mounting point, and surrounding suspension/air spring components. Note the orientation of the end link (which end is up, which way bushings face) and photograph for reference. Confirm the link is the failed component and not the sway bar bushing brackets.
2. 2

   Apply penetrating oil
   Apply penetrating oil to both the upper (sway bar) and lower (suspension/control arm) sway bar link stud threads. Allow several minutes to soak. Do not allow oil to contact air suspension bellows or brake components.
3. 3

   Loosen the upper sway bar link nut
   Insert the appropriate Allen/hex key into the end of the link stud to hold it stationary. Using a wrench on the nut, break loose and remove the upper nut where the link attaches to the sway bar. If the stud spins freely and the nut will not break loose, stop and consult procedure for stud-spin removal — do not damage the sway bar.
   ⚠Do not use an impact gun on the stud without holding it — you can shear or gall the threads.
4. 4

   Loosen the lower sway bar link nut
   Repeat the same hold-and-turn procedure on the lower end of the link, where it attaches to the suspension knuckle/control arm. Remove the nut.
5. 5

   Remove the end link
   Separate the link from both the sway bar and the lower mount. If suspension is unloaded and the sway bar has tension on it, you may need to gently pry the bar to align the stud through the eyelet. Do not pry against the air spring, brake line, wiring harness, or any orange cable (none should be present in this area, but verify).
   ⚠If you encounter any orange cable in the work area, STOP. It does not belong here — verify you are working on the correct vehicle/area.
6. 6

   Compare old and new parts
   Lay the new manufacturer-specified end link next to the removed unit. Verify length, stud orientation, ball joint angle, and that any boots/seals are intact on the new part. The two ends of a sway bar link are sometimes not interchangeable — install in the correct orientation.
7. 7

   Install the new end link
   Position the new link in the same orientation as the original. Thread both nuts on by hand — do not cross-thread. Ensure bushings/washers are seated correctly per the new part's design.
8. 8

   Torque the sway bar link nuts
   Hold each stud with an Allen key and torque each nut (upper and lower) to specification using a calibrated torque wrench. Both ends get the same torque value.
   ⚠Holding the stud with the Allen key is mandatory — torque cannot be measured accurately if the stud is spinning.

Reassembly

1. Reinstall the rear wheel. Snug the lug nuts in a star pattern.
2. Lower the vehicle to the ground.
3. Final-torque the lug nuts to OEM specification — refer to Tesla Service Manual for Cybertruck.
4. Reconnect the 48V low-voltage battery using the manufacturer-specified procedure.
5. Power up the vehicle and exit Jack/Service Mode for the air suspension.
6. Allow the air suspension to re-level to its normal ride height before driving.

Verification

• With the vehicle at normal ride height on level ground, visually confirm the new link is centered and not binding at either ball joint.
• Bounce the rear corner by hand — listen for clunks, knocks, or rattles from the sway bar/link area.
• Test drive at low speed over uneven pavement and through gentle turns. The rear should feel planted with no clunking from the previously-failed side.
• Check the touchscreen for any new chassis, suspension, or stability control fault messages. The Cybertruck will often log a fault if a suspension component was reporting issues prior to repair — clear codes if necessary.
• Re-inspect the link nut torque and look for any movement marks after the first 100-200 miles of driving.
• While under the vehicle, take the opportunity to note service-interval items that may be due: brake fluid (every 2 years), cabin air filter (every 2 years), and rear drive unit gear oil (Tesla's current guidance is no longer 'lifetime' — initial service around 12,500 mi, then every 25,000–50,000 mi depending on use). Tire rotation is recommended every 6,250 mi on Cybertruck due to weight and torque.
