Replacement of the rear sway (anti-roll) bar on a 2024 Model X. The rear subframe and air suspension make this slightly more involved than a typical sway bar job; the vehicle must be supported correctly with air suspension placed in service mode.

Warnings

Tools required

Parts

• Rear sway bar × 1 — OEM Tesla Model X rear stabilizer bar
• Sway bar bushings × 2 — OEM bushing set sized for the replacement bar
• Sway bar end links (recommended replacement if original) × 2 — OEM Model X rear stabilizer link

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. Before exiting, enable Jack Mode in the touchscreen (Service > Jack Mode) to disable air suspension self-leveling.
4. Disconnect the 12V low-voltage battery located in the frunk (lift carpet/access panel and remove the negative terminal).
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. Be aware of falcon door clearance overhead if using a two-post lift; do not open rear falcon doors while vehicle is raised.
8. Raise the vehicle on Tesla-approved lift points and support securely. Remove rear wheels if needed for sway bar end link access.

Procedure

1. 1

   Inspect and photograph factory routing
   Before any disassembly, photograph the rear sway bar, end links, brackets, and any wiring/lines routed near the bar. The rear suspension area on Model X includes ride height sensor wiring and air suspension lines that must not be pinched or rerouted incorrectly.
2. 2

   Remove rear underbody aero shielding
   Remove the rear underbody panel(s) covering the subframe area. Use the manufacturer-specified plastic fastener tool to release push-pin clips without breaking them. Set hardware aside in order.
3. 3

   Disconnect sway bar end links
   At each rear sway bar end link, hold the link's internal shaft with an Allen key while loosening the nut securing the link to the sway bar. Separate the link from the sway bar end. If end links are corroded or worn, replace them.
   ⚠Do not impact-gun the link nut without holding the internal shaft — the ball stud will spin and the boot will be destroyed.

4. 4

   Support sway bar and remove bracket bolts
   Support the sway bar with a transmission jack or have an assistant hold it. Remove the two bracket bolts on each side that secure the sway bar bushings/brackets to the subframe.

5. 5

   Maneuver sway bar out of vehicle
   Carefully lower and rotate the sway bar around the rear subframe and exhaust-equivalent components (none on EV, but air suspension lines, brake lines, and ride height sensor linkages must be avoided). Take care not to damage any harness or pneumatic line.
   ⚠Air suspension hard lines are plastic and route near the rear subframe — do not lever the sway bar against them.
6. 6

   Transfer or replace bushings and brackets
   Slide off old bushings and inspect the brackets. Install new bushings on the new sway bar in the same orientation as removed (note the slit direction and any flats indexed to the bar). Lubricate only with the bushing manufacturer's specified lubricant — do not use petroleum grease on rubber bushings.
7. 7

   Install new sway bar
   Position the new sway bar into the vehicle, aligning bushing brackets to the subframe mounting points. Hand-thread all four bracket bolts before torquing any of them.
8. 8

   Torque sway bar bracket bolts
   Torque the sway bar bracket bolts evenly in a cross pattern to specification.

9. 9

   Reattach end links
   Reconnect each end link to the new sway bar. Hold the end link's internal shaft with an Allen key and torque the nut to specification. Confirm boots are intact and seated.

10. 10

    Reinstall underbody shielding
    Reinstall the rear underbody aero panel(s) using new push-pin clips where any were broken. Confirm all clips are fully seated — loose aero panels create wind noise and reduce range.

Reassembly

1. Reinstall rear wheels (if removed) and torque lug nuts to OEM specification — refer to Tesla Service Manual.
2. Lower the vehicle to the ground.
3. Reconnect the 12V battery negative terminal in the frunk.
4. Close the frunk and allow the vehicle to wake; the air suspension will exit Jack Mode automatically or can be exited via the touchscreen.
5. Allow the air suspension to self-level before driving.

Verification

• Verify no warning messages on the instrument cluster related to suspension, ride height, or stability control.
• With the vehicle on the ground, visually confirm the sway bar sits centered with equal bushing exposure on both sides.
• Test drive at low speed and perform gentle left/right transitions; listen for clunks indicating loose end links or bracket bolts.
• Recheck sway bar bracket and link torque after the first 100 miles.
• While the vehicle is on the lift for this job, this is a good opportunity to inspect rear control arm bushings, ball joints, air strut condition, and brake fluid age (Tesla recommends brake fluid replacement every 2 years regardless of mileage).
