Replacement of a rear sway bar (anti-roll bar) end link on a 2024 Model X Long Range. The rear suspension is aluminum-intensive and the vehicle uses standard air suspension, which requires Jack Mode before lifting.

Parts

• Rear Sway Bar End Link (OEM Tesla Model X 2024) × 1 — Manufacturer-specified rear sway bar link assembly — verify by VIN

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with 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 low-voltage battery, located in the frunk (similar position to Model S). Refer to Tesla's documented disconnect procedure for the under-frunk-cover access panel.
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. Before disconnecting 12V: enable Jack Mode via the touchscreen (Controls → Service → Jack Mode) to lock out the air suspension self-leveling. Jack Mode must be set BEFORE 12V disconnect because the screen will be unavailable after.
7. Chock the front wheels.
8. Loosen rear lug nuts/bolts while the vehicle is on the ground.
9. Falcon doors: keep them closed during the job — opening with the vehicle on stands at uneven height can stress hinge sensors.

Procedure

1. 1

   Raise and support the rear of the vehicle
   Using Tesla-approved jack pads at the designated rear jack points, raise the rear of the vehicle and support it on rated jack stands. Confirm the vehicle is stable before going underneath.
   ⚠️Never work under a Model X supported only by a jack — the curb weight exceeds 5,400 lb.
2. 2

   Remove the rear wheel
   Remove the lug bolts and pull the rear wheel on the side being serviced. Set aside on a soft surface to avoid scratching the finish.
3. 3

   Locate the rear sway bar end link
   Identify the end link connecting the rear sway (anti-roll) bar to the suspension upright/control arm. Inspect the bushings, boots, and ball-stud for damage or play. Note routing of any nearby wiring or sensor harnesses so they can be avoided.
   ⚠Do not pry against or pinch ABS/wheel-speed sensor wiring, ride-height sensor links, or air suspension lines.
4. 4

   Apply penetrating oil if needed
   If the link nuts appear corroded, apply penetrating oil to both upper and lower nut/stud junctions and allow it to soak for several minutes.
5. 5

   Loosen the upper end link nut
   Hold the ball stud with the appropriate Allen/hex key (size per OEM) and loosen the upper nut with a wrench. Do not allow the stud to spin in its socket.
   ⚠Spinning the stud will destroy the internal ball joint and may damage the sway bar tab.
6. 6

   Loosen the lower end link nut
   Repeat the same hold-and-loosen procedure on the lower nut. Once both nuts are removed, withdraw the end link.
7. 7

   Inspect mating surfaces
   Inspect the sway bar tab and the suspension arm mounting hole for elongation, cracks, or corrosion. Confirm the sway bar bushings and brackets are intact — if the bracket bolts appear disturbed, verify they are properly torqued during reassembly.
   Torque spec

   Sway Bar Bracket Bolts47 Nm (35 lb-ft)
8. 8

   Install the new sway bar end link
   Position the new link with correct orientation (note any directional markings from the manufacturer). Hand-thread both upper and lower nuts onto the studs to ensure clean engagement.
9. 9

   Torque the end link nuts
   Hold each ball stud with the Allen key and torque the nuts to the verified specification. Torque both upper and lower nuts.
   Torque spec

   Sway Bar Link Nuts55 Nm (41 lb-ft)

Reassembly

1. Reinstall the rear wheel and snug the lug bolts.
2. Lower the vehicle until the wheel just contacts the ground, then final-torque the lug bolts to OEM specification — refer to Tesla Service Manual.
3. Fully lower the vehicle and remove jack stands.
4. Reconnect the 12V battery in the frunk and reinstall any covers.
5. Close the frunk and verify the vehicle powers up normally.
6. Exit Jack Mode via the touchscreen — the air suspension will self-level back to the selected ride height. Allow it to complete leveling before driving.

Verification

• With the vehicle at normal ride height, push down firmly on the rear corner — there should be no clunk from the sway bar area.
• Take a short, low-speed test drive over uneven pavement and listen for clunks or rattles from the rear suspension on body roll (e.g., gentle slalom).
• Recheck the link nuts after the first 100 miles to confirm they remain at the specified torque.
• Confirm no suspension or chassis fault messages appear on the touchscreen, and that the air suspension levels correctly at all four corners.
• While the vehicle is on stands is also a convenient time to inspect Tesla service-interval items: brake fluid condition (replace every 2 years), cabin air filter age (every 2 years, or 3 years if HEPA-equipped), tire rotation interval (every 6,250 mi), and rear drive unit gear oil service history (initial 12,500 mi, then 25,000–50,000 mi).
