Sway Bar - Rear

Replacement of the rear sway (anti-roll) bar on a 2024 Tesla Cybertruck Dual Motor. The truck uses standard air suspension; suspension must be at service height and unloaded at the links before disconnecting.

Warnings

Tools required

Parts

• Rear sway bar × 1 — Cybertruck rear sway bar — refer to Tesla EPC
• Sway bar bushings (typically replaced with bar) × 2 — OEM rear sway bar bushing kit
• Sway bar end links (recommended replacement if worn) × 2 — OEM rear sway bar end link

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. Disconnect the 48V low-voltage battery per Tesla service procedure (Cybertruck uses 48V — NOT 12V). Refer to architecture notes; the disconnect location and procedure differ from other Teslas.
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal (800V on Cybertruck).
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 lifting: enter Service Mode / Jack Mode via the touchscreen to disable air suspension self-leveling.
7. Raise the vehicle on a lift rated for Cybertruck weight using Tesla-specified lift points. Allow the rear suspension to hang or support the rear lower control arms with stands at ride height per Tesla guidance.
8. Remove rear wheels if needed for access (note: not always required for sway bar — assess first).

Procedure

1. 1

   Inspect work area
   Visually confirm the rear sway bar location, its two chassis-mounted bracket positions, and both end links connecting to the rear suspension. Identify and trace any wiring harnesses, air suspension lines, or HV cabling routed near the bar so they can be avoided. Confirm no orange HV cabling is in the immediate work path.
   ⚠️If orange cable is routed within the work area, stop and reassess routing before proceeding.
2. 2

   Disconnect sway bar end links (both sides)
   While holding the end link shaft with an Allen/hex key to prevent rotation, loosen and remove the nut securing each end link to the sway bar. Repeat on the opposite side. If reusing the links, inspect ball joints and boots for damage.

3. 3

   Support the sway bar
   Place a transmission jack or have a helper support the bar before unbolting the brackets. The bar is heavy and awkward — do not let it drop.
4. 4

   Remove sway bar bracket bolts
   Loosen and remove the bolts securing each sway bar bracket (saddle clamp) to the chassis/subframe. Set bolts aside and inspect threads. Remove the brackets and rubber bushings.

5. 5

   Maneuver sway bar out
   Carefully work the sway bar down and out of the chassis, routing it around the rear subframe, control arms, and any cabling. Take care not to contact the stainless underbody shields or any orange cabling.
   ⚠Do not pry against air suspension components, cooling lines, or HV cabling. Maneuver only with the bar in hand.
6. 6

   Transfer or replace bushings
   Install new sway bar bushings on the new bar (or onto the old bar if reusing). Lubricate only with the bushing manufacturer-specified silicone grease — do not use petroleum grease, which will degrade the rubber.
7. 7

   Install new sway bar
   Position the new sway bar into place, aligning the bushings with the chassis mounting points. Loosely install the bracket bolts so the bar can still shift slightly for end link alignment.
8. 8

   Torque sway bar bracket bolts
   Once the bar is centered and the brackets are seated correctly, torque all sway bar bracket bolts to specification.

9. 9

   Reconnect end links
   Reconnect each end link to the sway bar. Hold the end link shaft with an Allen/hex key and torque the nut to specification on both sides.

    Reinstall wheels (if removed)
    Reinstall rear wheels and torque lug nuts in a star pattern to specification.

Reassembly

1. Lower the vehicle to the ground.
2. Reconnect the 48V low-voltage battery using the Tesla-specified procedure.
3. Exit Service Mode / Jack Mode via the touchscreen and allow the air suspension to re-level normally.
4. Re-torque wheel lug nuts to spec after lowering, in star pattern.
5. Verify no warning messages on the center display related to suspension, ride height, or air suspension calibration.

Verification

• Confirm no abnormal warnings on the touchscreen after waking the vehicle.
• With the vehicle at normal ride height, visually inspect that the sway bar is centered and that both bushings are seated squarely in their brackets.
• Confirm both end links are tight and the bar moves with suspension articulation (push down on one rear corner; opposite side should respond).
• Take a short, low-speed road test: listen for clunks over bumps and confirm no body-roll asymmetry in turns.
• Re-inspect bolts for movement (paint mark or torque-seal recommended) after the first 100–200 miles.
• While under the vehicle, this is a good opportunity to check rear drive unit fluid condition — Tesla now recommends inspection around 12,500 mi initial and every 25,000–50,000 mi thereafter, contrary to older 'lifetime' guidance.
