Sway Bar Bushing - Rear

Replace the rear sway bar (stabilizer bar) bushings on a 2024 Tesla Cybertruck Cyberbeast. The bushings sit inside the brackets that clamp the sway bar to the rear subframe; this is a straightforward suspension job but requires care around the truck's air suspension and 48V architecture.

Tools required

Parts

• Rear sway bar bushings (manufacturer-specified for Cybertruck rear) × 2 — Tesla Cybertruck rear stabilizer bar bushing — refer to Tesla Service Manual / parts catalog

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 a 48V LV system, not 12V — confirm the correct disconnect point in the Tesla Service Manual before proceeding).
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. From the touchscreen, enable Jack Mode / Service Mode to disable air suspension self-leveling before lifting.
7. Chock the front wheels.
8. Loosen the rear lug nuts slightly while the wheels are still on the ground (only if wheel removal is needed for access).
9. Raise the rear of the vehicle at the manufacturer-specified lift points and support on rated jack stands. Confirm the truck is stable before going underneath.
10. Inspect the rear sway bar, end links, and surrounding area. Note bracket orientation and bushing slit position before disassembly.

Procedure

1. 1

   Access the rear sway bar
   If equipped, remove any rear underbody aero shielding or splash panels needed to access the rear sway bar brackets. Use a trim tool on plastic clips; do not pry against HV cabling or coolant lines.
   ⚠Identify any orange HV cabling and route tools clear of it before working in the area.
2. 2

   Support the sway bar
   Place a transmission jack or a jack with a wide pad lightly under the center of the sway bar to support its weight once the brackets are released. Do not lift — just support.
3. 3

   (Optional) Disconnect sway bar end links if needed for clearance
   If bushing removal requires lowering the sway bar significantly, hold the end-link stud with an Allen key and remove the sway bar link nut at one or both ends. On many Cybertruck rear setups, bracket-only removal is sufficient and end-link disconnection is not required — evaluate clearance first.
   ℹ️If you disconnect end links, mark left/right orientation so they are reinstalled on their original side.

   Remove the sway bar bracket bolts
   Unbolt the two sway bar bushing brackets from the rear subframe / cradle. Support the sway bar as the brackets release. Set the brackets aside and inspect them for cracks, distortion, or corrosion.

5. 5

   Lower the sway bar enough to slide bushings off
   Carefully lower the sway bar a few inches — only as much as needed to access the bushings. Do not stress brake lines, sensor harnesses, air suspension lines, or any orange HV cabling routed in the area.
   ⚠️Do not allow the sway bar to fall freely. Damage to nearby HV cables or air suspension lines can be catastrophic.
6. 6

   Remove the old bushings
   Open the slit on each bushing and slide it off the sway bar. Note the orientation of the slit (typically facing forward or upward depending on design) and any directional markings. Clean the sway bar contact area with a clean rag — no solvents that attack rubber.
7. 7

   Install the new bushings
   Apply a thin film of silicone-safe rubber lubricant to the inside of each new bushing (do NOT use petroleum grease — it will degrade rubber). Slide the new bushings onto the sway bar in the same orientation as the originals, aligning any locating tab or flat with its mating feature on the bar.
   ⚠Bushing orientation matters. An incorrectly clocked bushing will bind and cause clunking or premature failure.
8. 8

   Reinstall the brackets
   Lift the sway bar back into position. Place each bracket over its bushing and start both bracket bolts by hand to avoid cross-threading. Once both bolts are started on each bracket, snug them evenly, then torque to specification.

   Reconnect end links (if disconnected)
   If the end links were removed, reinstall the link nuts. Hold the end-link stud with an Allen key in the provided socket on the stud and torque the nut to specification. Do not spin the stud in the bushing.

    Reinstall underbody shielding
    Reinstall any aero/splash panels removed for access. Replace any broken plastic clips with new ones — Cybertruck underbody aero is critical for range and thermal management.

Reassembly

1. Confirm no tools or rags remain on the subframe or near the sway bar.
2. Lower the vehicle to the ground.
3. If wheels were removed, torque lug nuts to OEM specification — refer to Tesla Service Manual.
4. Reconnect the 48V low-voltage battery.
5. Exit Jack Mode / Service Mode from the touchscreen and allow the air suspension to self-level.

Verification

• With the vehicle at normal ride height, visually verify both bushing brackets are flush against the subframe with no gap, and that the bushings are not pinched or twisted.
• Confirm no warning messages on the touchscreen related to suspension, ride height, or vehicle dynamics.
• Road test at low speed over expansion joints and small bumps; listen for clunks from the rear. A correctly installed bushing should be silent.
• At highway speed on a smooth road, confirm there is no rear-end shimmy or unusual body motion. Steer-by-wire feedback should feel unchanged from before the repair.
• Re-inspect bracket bolts after the first 100–200 miles of driving to confirm they have not loosened.
• While underneath, this is a good opportunity to note Tesla service intervals that overlap with suspension work: brake fluid is recommended every 2 years regardless of mileage, and tire rotation every ~6,250 mi due to the Cybertruck's weight and instant torque.
