Replace the rear control arm bushing on a 2024 Tesla Cybertruck Dual Motor AWD. The Cybertruck uses a multi-link rear suspension with air springs; bushing replacement requires removing the affected control arm and pressing in a new bushing using a hydraulic press or in-vehicle bushing tool.

Warnings

Tools required

Parts

• Rear control arm bushing (manufacturer-specified for Cybertruck rear suspension) × 1 — Tesla OEM rear control arm bushing — confirm by VIN
• Control arm bolts (replace if Tesla specifies single-use TTY hardware — verify in service manual) × 2 — OEM specification

Preparation

1. Park on level ground, place in P, engage the electronic parking brake.
2. Exit ALL doors with the key fob/phone key carried away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even though this is a non-HV job.
3. Place the air suspension in Service Mode / Jack Mode via the touchscreen so the system does not attempt to self-level during the repair.
4. Disconnect the 48V low-voltage battery per the Cybertruck service manual (location and disconnect procedure differ from 12V Teslas — verify before cutting power).
5. DO NOT touch, cut, or pierce ANY orange cable — these are 800V high-voltage and lethal.
6. If you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
7. Chock the front wheels. Break rear lug nuts loose while tires are on the ground.
8. Raise the rear of the vehicle on a lift rated for Cybertruck weight, or support on heavy-duty jack stands at the manufacturer-specified lift points.
9. Remove the rear wheel on the affected side.

Procedure

1. 1

   Identify the affected control arm
   The Cybertruck rear suspension uses multiple links. Confirm which control arm contains the failed bushing (commonly the lower lateral or trailing arm). Inspect for cracking, separation, or fluid weeping from hydraulic bushings. Photograph orientation and indexing marks before disassembly.
2. 2

   Support the rear knuckle
   Place a transmission jack or sturdy stand under the rear knuckle/hub assembly to support it once the control arm is freed. This prevents the half-shaft, brake line, and air strut from carrying suspension load.
   ⚠Do not allow the knuckle to hang on the half-shaft or brake line — both can be damaged.
3. 3

   Disconnect the rear sway bar link (if it interferes)
   If the sway bar end-link blocks access to the control arm bolts, remove it. Hold the link's internal shaft with an Allen key while loosening the nut. Set the link aside.
   Torque spec

   Sway Bar Link61 Nm (45 lb-ft)
4. 4

   Release any sensor or wiring brackets on the control arm
   The Cybertruck has ride-height sensors and may route wiring or air lines along rear suspension members. Carefully unclip any harnesses, sensors, or air lines from the control arm before removal. Do NOT stretch or strain ride-height sensor linkages.
   ⚠Damaged ride-height sensors will cause air suspension faults requiring Tesla-specific calibration.
5. 5

   Mark control arm orientation and alignment cams
   Before loosening, paint-mark the position of any eccentric/cam alignment bolts so the arm can be reinstalled in the same alignment position. This minimizes (but does not eliminate) the need for a post-repair alignment.
6. 6

   Remove the control arm inboard and outboard fasteners
   Loosen and remove the inboard (subframe-side) and outboard (knuckle-side) bolts/nuts securing the control arm. If the outboard end uses a tapered ball joint with a castle nut and cotter pin, remove the cotter pin and separate the joint using a manufacturer-specified ball joint separator — do not strike the knuckle with a hammer.
   ⚠Some Tesla suspension fasteners are single-use torque-to-yield. Verify in the service manual whether new bolts are required.
   Torque spec

   Control Arm Bolts165 Nm (122 lb-ft)

   Ball Joint Nut88 Nm (65 lb-ft)
7. 7

   Remove the control arm from the vehicle
   Maneuver the arm out of the vehicle. Note any shims, washers, or alignment hardware and keep them with the arm.
8. 8

   Press out the failed bushing
   Secure the control arm in a hydraulic press using bushing driver/receiver cups sized for the Cybertruck arm. Press the old bushing straight out, supporting the arm so it does not deform. If the bushing is bonded with rubber to a steel sleeve, you may need to cut the rubber first to release the outer sleeve. Do NOT heat aluminum control arms with an open flame.
   ⚠Heating an aluminum arm above ~200°C anneals it and ruins its strength. Use mechanical pressing only.
9. 9

   Inspect the control arm bore
   Clean the bore. Check for cracking, ovaling, or corrosion. If the bore is damaged, replace the entire control arm — do not attempt to install a new bushing in a compromised arm.
10. 10

    Press in the new bushing
    Orient the new bushing per Tesla service manual indexing (voids/arrows often must align with the load axis). Press the bushing in evenly using the correct receiver cup until fully seated to the manufacturer-specified depth. Do not lubricate rubber bushings with petroleum products — use only soapy water or a manufacturer-approved assembly lube if specified.
    ⚠Incorrect bushing clocking will cause premature failure and ride-height/alignment issues.

Reassembly

1. Reinstall the control arm into the vehicle, aligning paint marks made before removal.
2. Hand-thread all control arm fasteners (use new bolts if specified by Tesla).
3. Reconnect the ball joint (if applicable). Tighten the Ball Joint Nut to 88 Nm (65 lb-ft) and install a NEW cotter pin — never reuse the old pin.
4. Reattach any wiring, ride-height sensors, and air lines to their original brackets.
5. Reinstall the sway bar link, holding the shaft with an Allen key while torquing.
6. Reinstall the rear wheel. Snug lug nuts.
7. Lower the vehicle so full weight is on the wheels (or place on drive-on ramps / alignment rack at ride height).
8. Final-torque the Control Arm Bolts to 165 Nm (122 lb-ft) WITH vehicle weight on the wheels.
9. Torque the Sway Bar Link to 61 Nm (45 lb-ft) and Sway Bar Link Nuts to 55 Nm (41 lb-ft).
10. Torque Wheel Lug Nuts to 136 Nm (100 lb-ft) in a star pattern.
11. Reconnect the 48V low-voltage battery.
12. Exit Service / Jack Mode via the touchscreen and allow the air suspension to self-level.

Verification

• Power up the vehicle and confirm no suspension, ride-height, or chassis fault messages appear on the touchscreen.
• Cycle the air suspension through all ride-height settings and confirm the vehicle levels evenly side-to-side and front-to-rear.
• Perform a low-speed test drive: listen for clunks, knocks, or binding from the rear suspension during turns and over bumps.
• Check for any new TPMS/ABS/stability faults — disconnecting the 48V LV battery occasionally requires module re-handshaking.
• Schedule a 4-wheel alignment. Even if eccentrics were marked, Cybertruck rear toe and camber should be verified after any control arm service.
• Re-inspect torque on Control Arm Bolts and Ball Joint Nut after the first 100–500 miles of driving.
• Note: This job is not part of a published Tesla service interval, but Cybertruck suspension components should be visually inspected during every tire rotation (~6,250 mi).
