Sway Bar - Rear

Replacement of the rear sway (anti-roll) bar on a 2024 Tesla Cybertruck Cyberbeast. The rear sway bar is mounted to the rear subframe with two bushing brackets and connects to the rear suspension via end links.

Warnings

Tools required

Parts

• Rear sway bar (OEM replacement) × 1 — Tesla Cybertruck rear sway bar — refer to Tesla EPC
• Sway bar bushings (recommended to replace with bar) × 2 — Manufacturer-specified rear sway bar bushing kit
• Sway bar end links (inspect; replace if worn) × 2 — Manufacturer-specified rear end link assembly

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 (Cybertruck uses 48V LV — locate per Tesla service documentation; do NOT assume 12V conventions).
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. Before disconnecting LV power, enter the touchscreen Service menu and activate Jack Mode / Transport Mode so the air suspension does not attempt self-leveling.
7. Raise the vehicle on a lift rated for Cybertruck weight, using the Tesla-specified lift points (reinforced pinch-weld pucks or factory pads).
8. Allow the rear suspension to hang at full droop (no jack stands under the rear control arms) so the sway bar is unloaded.
9. Remove any underbody aero/skid shielding necessary to access the rear sway bar — note clip and fastener locations for reinstallation.

Procedure

1. 1

   Inspect and document
   Photograph the rear sway bar orientation, bracket positions, end link orientation (which side of the bar/upright), and any routing of nearby wiring or air suspension lines. The rear of the Cybertruck contains air spring lines and ride-height sensor wiring that must not be pinched during reassembly.
   ⚠Do not pry against air suspension lines or ride-height sensor harnesses.
2. 2

   Disconnect rear sway bar end links (both sides)
   Locate the sway bar end link nut at each end of the bar. Hold the link's internal shaft with the appropriate Allen/hex key to prevent it from spinning while loosening the nut with a wrench. Remove the nut and separate the link from the sway bar. If the link will be reused, inspect the ball joint for play and the boot for tearing.

3. 3

   Support the sway bar
   Place a transmission jack or have an assistant support the sway bar before removing the bracket bolts. The bar is heavy and will drop once the brackets are released.
4. 4

   Remove sway bar bracket bolts
   Remove the bolts securing each sway bar bushing bracket to the rear subframe. Note the bracket orientation (typically there is an alignment tab or directional bushing slit that must face a specific direction).

5. 5

   Maneuver the sway bar out
   Carefully lower and rotate the sway bar to clear the rear subframe, exhaust-equivalent crossmembers, drive unit housing, and any wiring. Do not contact orange HV cabling or the rear drive unit case. Route the bar out through the side with the most clearance.
   ⚠️If you see any orange cabling in the path of the sway bar, STOP. Do not pry, lever, or scrape against it.
6. 6

   Transfer bushings and brackets
   Slide the old bushings off the bar (if reusing brackets). Inspect bushings for cracking, glazing, or wallowing — replacement is strongly recommended any time the bar is removed. Install new bushings in the correct orientation (slit typically faces forward or as marked) onto the new sway bar. Apply only the bushing lubricant supplied by the manufacturer; do NOT use petroleum grease, which destroys rubber.
7. 7

   Install the new sway bar
   Maneuver the new sway bar into position, mirroring the removal path. Position the bushings against the subframe mounting points and start the bracket bolts by hand to avoid cross-threading.
8. 8

   Torque bracket bolts
   Tighten the sway bar bracket bolts evenly, alternating side-to-side, to the verified specification.

9. 9

   Reconnect end links
   Install the end link studs into the sway bar ends. Hold the internal shaft with an Allen/hex key and tighten the nut to specification. Verify boots are not twisted and ball joints articulate freely.

    Reinstall underbody shielding
    Reinstall any aero panels or skid shielding removed for access. Replace any broken plastic clips — missing clips will cause aero panel flutter and reduced range. Torque shield fasteners to OEM specification — refer to Tesla Service Manual.

Reassembly

1. Double-check that no tools, rags, or hardware remain on the subframe or near suspension components.
2. Verify that no wiring harnesses or air suspension lines have been pinched, rerouted, or contacted by the new sway bar.
3. Lower the vehicle so suspension is loaded at normal ride height before final torque verification of any fastener that passes through a rubber bushing (per the manufacturer's bushing-loading guidance).
4. Reconnect the 48V low-voltage battery, observing correct polarity and any required reconnection sequence for the Cybertruck LV system.
5. Exit Jack/Service Mode via the touchscreen and allow the air suspension to self-level. Confirm no fault messages appear.

Verification

• With the vehicle at ride height, visually confirm the sway bar is centered, both bushings are seated, and end links are perpendicular without preload binding.
• Check the touchscreen for any chassis, suspension, or ride-height fault codes.
• Test drive on a smooth road and then over uneven pavement: listen for clunks (loose end link or bracket), and confirm the rear feels planted in cornering with no excessive body roll.
• Recheck sway bar bracket bolts and end link nuts after the first 100–200 miles for any loosening.
• Note: Sway bar service is not on a Tesla scheduled interval, but while the vehicle is in the air, this is an opportune time to verify tire rotation interval (Tesla recommends every 6,250 mi) and to inspect rear control arm bushings, ball joints, and air spring boots for wear.
