Replace the rear sway bar (stabilizer bar) on a 2024 Model Y Long Range AWD. Job requires lifting the vehicle, supporting the rear subframe area, and disconnecting both end links and bushing brackets to drop the bar.

Warnings

Tools required

Parts

• Rear sway bar (stabilizer bar) — Model Y AWD specific × 1 — OEM Tesla rear stabilizer bar assembly for 2024 Model Y LR AWD
• Sway bar bushings × 2 — OEM rubber bushings sized for replacement bar diameter
• Sway bar end links (recommended if original showing wear) × 2 — OEM 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. Disconnect the 12V low-voltage battery (located under the rear seat / rear cargo area trim on 2024 Model Y). Refer to Tesla's service documentation for exact access on your build.
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. Enable Jack Mode via the touchscreen (Service menu) before lifting to disable air/level functions and prevent fault codes — note: 2024 Model Y is coil-sprung, but Jack Mode still suppresses sensor faults.
7. Loosen rear lug nuts while wheels are on the ground.
8. Lift the rear of the vehicle at the manufacturer-specified jack points using approved pucks; support on stands rated for the vehicle's weight.
9. Remove rear wheels.

Procedure

1. 1

   Remove rear underbody aero panel
   Remove the rear underbody aerodynamic shield/diffuser fasteners (mix of plastic push clips and bolts) to access the rear suspension and sway bar. Set hardware aside in order — Tesla uses several different fastener lengths.
   ⚠Do not let the panel hang on its remaining clips — support it as you remove the last fasteners.
2. 2

   Support the rear suspension
   Place a jack under the rear lower control arm or subframe to neutralize suspension load. This relieves preload on the sway bar end links and makes removal easier.
3. 3

   Disconnect sway bar end links (both sides)
   Locate the rear sway bar end links connecting the bar ends to the suspension. Hold the link's internal shaft with an Allen key (most Tesla links have a hex broach in the stud) and remove the nut. Separate the link from the sway bar. Inspect link bushings/ball joints for play; replace if worn.
   ℹ️If the stud spins instead of breaking loose, apply penetrating oil and use a back-up wrench on the hex feature.

4. 4

   Mark sway bar orientation
   Before unbolting the brackets, mark the bar's orientation (up/forward) with paint or tape. Note bushing positions relative to any locating tabs on the bar — bushings must reinstall in the same locations.
5. 5

   Remove sway bar bushing brackets
   Support the sway bar with a hand or transmission jack. Remove the bracket bolts securing the two bushing clamps to the rear subframe. Lower the bar carefully — it is heavy enough to fall if unsupported.
   ⚠Do not pry against or near the HV battery case. Maintain clearance from any orange cabling routed near the rear subframe.

6. 6

   Maneuver the sway bar out
   Rotate and walk the bar out from between the subframe, exhaust-area heat shield (if equipped), and rear suspension components. Clearance is tight; you may need to drop the rear subframe slightly per Tesla's published procedure if the bar will not clear — STOP and consult the service manual rather than forcing it.
   ⚠Forcing the bar past wiring harnesses or HV components can cause expensive damage. If it doesn't come out with reasonable effort, additional disassembly is required.
7. 7

   Transfer / install bushings on new bar
   Slide new bushings onto the new sway bar in the marked positions. Use only rubber-safe assembly lubricant (silicone paste or soapy water) — never petroleum grease, which destroys the rubber. Align bushings against any locating collars on the bar.
8. 8

   Install new sway bar
   Position the new sway bar into the vehicle in the same orientation as the original. Loosely install the bushing bracket bolts on both sides — do not torque yet. Confirm the bar is centered side-to-side.
9. 9

   Reconnect end links
   Reconnect both end links to the bar ends, holding the stud with an Allen key while tightening the nut. Use new self-locking nuts if the originals show damage.

    Torque bushing brackets
    Torque both sway bar bushing bracket bolts to specification, alternating sides in stages.

Reassembly

1. Reinstall the rear underbody aero panel with all original fasteners; missing clips cause wind noise and panel loss at highway speed.
2. Reinstall rear wheels and hand-snug lug nuts.
3. Lower vehicle to the ground.
4. Final-torque lug nuts in a star pattern (see torqueRefs: Wheel Lug Nuts).
5. Reconnect the 12V low-voltage battery and reinstall any trim removed for access.
6. Exit Jack Mode and allow the vehicle to complete its wake-up self-checks.

Verification

• Confirm no warning messages on the touchscreen after reconnecting 12V (expect a few transient alerts that should clear after a drive cycle).
• Test drive at low speed first, listening for clunks over bumps — a properly installed sway bar is silent.
• At highway speed, vehicle should track straight and resist body roll equally in left/right transitions.
• Re-inspect end link nuts and bracket bolts after the first 100-200 miles for any loosening.
• While the vehicle is in the air, this is a good opportunity to inspect rear tire wear (Model Y wears rear tires aggressively; rotation is recommended every 6,250 mi) and check brake fluid age — Tesla recommends brake fluid replacement every 2 years.
