Replace a failed air spring on a 2024 Model X Long Range with standard adaptive air suspension. The Model X uses air springs at all four corners; this procedure covers a single corner replacement with vehicle properly supported and air system depressurized via service mode.

Warnings

Tools required

Parts

• Air spring assembly (corner-specific, Model X 2024) × 1 — OEM Tesla air spring — order by VIN and corner (FL/FR/RL/RR)
• Upper strut tower nuts (replace if single-use per OEM) × 3 — OEM specification
• Lower mounting hardware (replace if specified single-use) × 1 — OEM specification

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. Before disconnecting 12V: enter Service Mode on the touchscreen and activate Jack Mode / Air Suspension Service Mode to lock height and depressurize the system. Confirm the corner being serviced has fully vented.
4. Disconnect the 12V low-voltage battery in the frunk (negative terminal first). Wait 2 minutes before proceeding.
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. Confirm falcon doors (if servicing a rear corner) are fully closed and will remain closed during the entire procedure.
8. Identify Tesla-approved lift/jack points on the rocker — never lift on the floor pan or HV battery case.
9. Loosen wheel lug nuts before lifting.

Procedure

1. 1

   Lift and support the vehicle
   Raise the vehicle on a lift using OEM jack pad locations, or jack at the rocker lift point and support with jack stands rated for the Model X curb weight (~5,400 lb). Confirm the air system is depressurized before any further disassembly.
   ⚠️Jacking on the HV battery case will cause catastrophic damage and possible thermal event.
2. 2

   Remove the wheel
   Remove the lug nuts and pull the wheel. Set aside on a surface that won't scratch the finish.
   Torque spec

   Wheel Lug Nuts136 Nm (100 lb-ft)
3. 3

   Access upper strut mount
   For a front corner: open the frunk, remove the trim/cowl panels as needed to expose the upper strut tower nuts. For a rear corner: remove the trunk side trim to access the upper mount. Use trim tools to avoid breaking aluminum-body clip bosses.
   ⚠Aluminum body — do not pry against painted surfaces.
4. 4

   Disconnect ride height sensor and air line
   Locate the ride height sensor link at the lower control arm and disconnect it carefully — these arms are fragile. Identify the pneumatic supply line at the top of the air spring. With the system confirmed depressurized, release the push-to-connect collar and withdraw the air line. Cap or cover the open line to keep contaminants out.
   ⚠️If you hear any hiss when releasing the air line, STOP — the system is still pressurized.
5. 5

   Support the lower control arm
   Place a transmission jack or floor jack with a wide pad under the lower control arm to support its weight. This prevents the arm from dropping when the strut/air spring is disconnected and protects the ball joint and bushings.
6. 6

   Disconnect sway bar end link (if required for clearance)
   If clearance is needed, separate the sway bar end link from the lower control arm. Hold the stud with an Allen key while loosening the nut.
   Torque spec

   Sway Bar Link Nuts55 Nm (41 lb-ft)
7. 7

   Remove lower air spring/strut bolt(s)
   Remove the lower mounting bolt(s) that secure the air spring/strut assembly to the lower control arm or knuckle, per the manufacturer-specified configuration for this corner. Retain the hardware for inspection; replace if the OEM specifies single-use fasteners.
   Torque spec

   Strut Bolts115 Nm (85 lb-ft)
8. 8

   Remove upper strut tower nuts
   From above, remove the upper strut tower nuts while supporting the air spring/strut assembly from below. Do not allow the assembly to fall.
   Torque spec

   Strut Tower Nuts50 Nm (37 lb-ft)
9. 9

   Extract the air spring assembly
   Carefully maneuver the air spring/strut assembly out of the wheel well. Inspect the upper mount, bump stop, and surrounding bushings for damage. Compare the new unit to the old one to confirm correct corner and part match.
   ⚠Do not clamp the air spring bladder in a vise — it will be destroyed.
10. 10

    Install the new air spring assembly
    Position the new assembly into the tower from below, align the upper studs, and start the upper nuts by hand. Then align the lower mount and start the lower bolt(s) by hand. Do not fully torque any fastener yet.
11. 11

    Torque upper strut tower nuts
    With the assembly seated and aligned, torque the upper strut tower nuts to specification.
    Torque spec

    Strut Tower Nuts50 Nm (37 lb-ft)
12. 12

    Torque lower strut/air spring bolt
    Torque the lower mounting bolt to specification. If the OEM procedure calls for final torque at ride height, snug here and final-torque after the vehicle is back on its wheels.
    Torque spec

    Strut Bolts115 Nm (85 lb-ft)
13. 13

    Reconnect air line and ride height sensor
    Push the pneumatic line fully into the new air spring fitting until it seats and locks — give it a firm tug to confirm engagement. Reconnect the ride height sensor link.
    ⚠An incompletely seated air line will leak under pressure and cause a suspension fault and possible vehicle drop.
14. 14

    Reconnect sway bar end link (if disconnected)
    Reinstall the sway bar end link, holding the shaft with an Allen key.
    Torque spec

    Sway Bar Link Nuts55 Nm (41 lb-ft)
15. 15

    Reinstall wheel and lower vehicle
    Reinstall the wheel and torque the lug nuts in a star pattern. Lower the vehicle so full weight is on the wheels before final-torquing any control arm fasteners that were loosened.
    Torque spec

    Wheel Lug Nuts136 Nm (100 lb-ft)

    Control Arm Bolts165 Nm (122 lb-ft)

Reassembly

1. Reinstall any frunk or trunk trim panels removed for upper mount access.
2. Reconnect the 12V battery (negative last). Close the frunk.
3. Re-enter the vehicle and exit Service Mode / Jack Mode via the touchscreen.
4. Allow the air compressor to repressurize the system. Listen for leaks at the new air spring connection — a steady hiss or repeated compressor cycling indicates a leak.
5. Perform a ride height calibration if prompted, or if the vehicle reports a suspension fault. This may require Tesla service software for a full recalibration.
6. Clear any suspension DTCs.

Verification

• Confirm no suspension warning messages on the instrument cluster or center display.
• Visually verify ride height is even side-to-side at the same corner pair (front-to-front, rear-to-rear) within OEM tolerance.
• Cycle the vehicle through Low / Standard / High ride height settings via the touchscreen and confirm all positions are reached without fault.
• After a 30-minute soak with the vehicle off, confirm the corner has not sagged (indicates a leak).
• Test drive and confirm no clunks, no pulling, and the air compressor does not run continuously.
• Note: this Model X is not on a Tesla-defined air suspension service interval, but Tesla recommends brake fluid replacement every 2 years and cabin filter every 2 years (3 years for HEPA) — note these in the customer's records if due.
