Replacement of a rear control arm bushing on a 2024 Tesla Cybertruck Cyberbeast Tri-Motor. The Cybertruck's rear multi-link suspension and air-spring system require careful unloading and final torque-down at ride height to avoid premature bushing failure.

Warnings

Tools required

Parts

• Rear control arm bushing (manufacturer-specified for Cybertruck rear suspension) × 1 — Refer to Tesla EPC for the specific rear arm being serviced
• Cotter pin for ball joint castle nut (if applicable to the disturbed joint) × 1 — OEM-spec cotter pin
• Control arm pivot bolt(s) — replace if Tesla specifies one-time-use × 1 — Refer to Tesla Service Manual for one-time-use designation

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 48V low-voltage battery per Tesla Service Manual procedure for Cybertruck (note: 48V architecture, not 12V — different connector and fusing).
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 low-voltage power, enter the touchscreen Service Menu and activate Jack Mode / Transport Mode to disable air suspension self-leveling.
7. Chock the front wheels. Loosen rear lug nuts while the vehicle is on the ground.
8. Identify which rear control arm bushing is being serviced (upper/lower/toe/camber link) and confirm against the Tesla EPC before ordering parts.
9. Inspect adjacent components (ball joints, sway bar end links, air spring, ride height sensor linkage) for damage before disassembly.

Procedure

1. 1

   Lift and support the vehicle
   Lift the Cybertruck using only the manufacturer-specified pinch-weld / frame lift points. Due to curb weight, ensure your lift is rated appropriately. Once lifted, support the rear subframe area with jack stands rated for the load. Allow the rear suspension to hang freely.
   ⚠Do NOT place lift arms on the HV battery pack, air spring reservoirs, or stainless underbody trays.
2. 2

   Remove the rear wheel
   Remove the rear lug nuts and pull the wheel. Set the wheel aside on its face to avoid scratching the finish.

3. 3

   Document and photograph the suspension geometry
   Before disturbing anything, photograph the control arm orientation, any alignment cams/eccentric bolts, and the position of any ride-height sensor linkage. Cybertruck rear alignment is sensitive and an alignment will be required after this job.
4. 4

   Disconnect the rear sway bar end link (if it interferes)
   If the sway bar end link blocks access to the control arm bushing being replaced, remove its nut while holding the stud shaft with an Allen key to prevent spinning.

   Sway Bar Link Nuts55 Nm (41 lb-ft)
5. 5

   Disconnect the ride height sensor link (if present on this arm)
   If a ride-height sensor link attaches to the arm being serviced, carefully unclip it. Do not bend or damage the sensor arm — replacements are expensive and require calibration.
6. 6

   Unload the suspension and separate the ball joint (if required by arm design)
   If the bushing replacement requires separating a ball joint, support the knuckle with a floor jack. Remove the cotter pin and ball joint castle nut, then separate using a non-marring separator. Do not strike the knuckle directly.
   ⚠Always replace the cotter pin with a new one on reassembly — never reuse.

7. 7

   Remove the control arm pivot bolt(s)
   Mark the position of any eccentric/cam alignment bolts before loosening. Remove the inboard pivot bolt(s) securing the arm to the subframe. The bolt(s) may be tight — use a breaker bar. Note bolt orientation for reassembly.

   Control Arm Bolts165 Nm (122 lb-ft)
8. 8

   Remove the control arm from the vehicle
   Maneuver the control arm out of the subframe pocket. Inspect bushing housing for corrosion or damage.
9. 9

   Press out the old bushing
   Using a hydraulic press or appropriate bushing removal tool, press the worn bushing out of the control arm. Support the arm properly to avoid bending. If the bushing is seized, apply penetrating oil and allow it to soak. Do not heat the arm beyond manufacturer guidance — aluminum arms can lose temper.
10. 10

    Clean and inspect the bushing bore
    Clean the bore with an appropriate solvent. Inspect for cracks, ovality, or corrosion. Replace the entire control arm if the bore is damaged.
11. 11

    Press in the new bushing
    Orient the new bushing per Tesla's service documentation (some bushings have a specific clocking for void/stiffness orientation). Press in straight and squarely until fully seated. Use only the manufacturer-specified bushing — aftermarket polyurethane substitutes can affect ride-height sensor calibration and tire wear.
12. 12

    Reinstall the control arm
    Position the arm back in the subframe pocket. Install the pivot bolt(s) by hand and finger-tighten only. Do NOT final-torque yet — bushings must be torqued at ride height.

    Reconnect ball joint, sway bar link, and ride height sensor
    Reattach the ball joint with a new cotter pin, reconnect the sway bar end link holding the shaft with an Allen key, and reconnect the ride height sensor link in its photographed position.

Reassembly

1. Reinstall the rear wheel and torque lug nuts to spec in a star pattern.
2. Lower the vehicle so the suspension supports the full weight of the truck at normal ride height.
3. With the truck at ride height, final-torque the control arm pivot bolt(s) to specification. This is CRITICAL — torquing while the suspension is hanging will pre-load the bushing and cause early failure.
4. Reconnect the 48V low-voltage battery per Tesla's reconnection sequence.
5. Exit Jack/Service Mode via the touchscreen and allow the air suspension to self-level.
6. Cycle the suspension through its height settings (if accessible) to confirm normal operation.

Verification

• Confirm no suspension or ABS/stability faults on the touchscreen after power-up.
• Verify air suspension reaches and holds standard ride height without leaks or warning messages.
• Inspect the new bushing area for proper seating and that no pivot bolt is proud or under-torqued.
• Perform a four-wheel alignment — required after any rear control arm/bushing replacement on Cybertruck. Cam bolts (if disturbed) must be reset by an alignment rack.
• Test drive at low speed first, then highway speed, listening for clunks or feeling for steering pull. Note: steer-by-wire means no traditional mechanical feedback; rely on dashcam/road feel and any chassis-control alerts.
• Re-inspect the bushing and pivot bolt torque after the first 100 miles as a sanity check.
• While the vehicle is in service, take the opportunity to check Tesla's recommended service intervals: brake fluid (every 2 years), cabin air filter (every 2 years), drive unit gear oil (initial 12,500 mi then 25,000–50,000 mi), and battery coolant inspection (4 years / 50,000 mi).
