Replace the front strut upper mount on a 2024 Tesla Cybertruck Cyberbeast. The Cybertruck uses standard air suspension up front, so the strut/spring assembly must be removed as a unit and the air line depressurized before disassembly.

Warnings

Tools required

Parts

• Front strut upper mount assembly (manufacturer-specified for Cybertruck front) × 1 — OEM Tesla Cybertruck front strut mount — verify by VIN
• Strut tower nuts (single-use if specified by Tesla) × 3 — OEM specification — replace if torque-to-yield
• Strut-to-knuckle bolt/nut set (replace if specified) × 1 — OEM specification

Preparation

1. Park on level ground, place in P, and engage the 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. Enter Service Mode / Jack Mode via the touchscreen to disable air suspension self-leveling and allow the system to settle.
4. Disconnect the 48V low-voltage battery (Cybertruck-specific — NOT a 12V system). Refer to architecture notes; the LV battery is located per Tesla service documentation for Cybertruck.
5. DO NOT touch, cut, or pierce ANY orange cable — these are 800V high-voltage and lethal.
6. 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.
7. Loosen front wheel lug nuts while the truck is on the ground.
8. Lift the vehicle at Tesla-designated front lift points using equipment rated for Cybertruck weight; support on jack stands.
9. Remove the front wheel on the side being serviced.
10. Protect the stainless exoskeleton fender edge with fender covers — the metal scratches and dents far more easily than aluminum body panels.

Procedure

1. 1

   Verify air suspension is depressurized
   Confirm Service Mode is active and the air suspension has settled. Locate the air line at the strut and, following Tesla service documentation, depressurize and disconnect the air line at the strut fitting. Cap the open line to prevent contamination.
   ⚠️Pressurized air struts can release stored energy violently. Never disconnect a strut air line that has not been confirmed depressurized.
2. 2

   Disconnect electrical connectors at the strut/knuckle
   Disconnect the wheel speed sensor harness, brake pad wear sensor (if equipped), and any ride-height/damper control connectors routed along the strut. Free the harnesses from their retaining clips so the strut can be lowered without tension on the wiring.
   ⚠Cybertruck connectors are 48V-architecture and may not match earlier Tesla designs — do not force-fit replacement clips from other models.
3. 3

   Disconnect the sway bar end link
   Hold the end link stud with an Allen/hex key and remove the nut securing the sway bar link to the strut/knuckle bracket. Swing the link clear.
   Torque spec

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

   Support the lower control arm
   Place a floor jack under the lower control arm to support the suspension's weight. This prevents the knuckle/half-shaft from dropping when the strut bolts are removed.
   ⚠Do not let the knuckle hang on the outer CV joint or brake hose.
5. 5

   Remove the strut-to-knuckle bolts
   Remove the bolts/nuts securing the lower end of the strut to the steering knuckle. Note bolt orientation. If bolts are torque-to-yield per Tesla specification, replace them on reassembly.
   Torque spec

   Strut-to-Knuckle Bolts122 Nm (90 lb-ft)
6. 6

   Remove upper strut tower nuts
   From inside the front compartment (frunk area), remove the trim/access cover as needed and remove the strut tower nuts retaining the upper mount. Have an assistant support the strut from below as the last nut is removed.
   ⚠The strut assembly is heavy. Do not allow it to fall — it can damage the air line, brake hose, or stainless body edge.
   Torque spec

   Strut Tower Nuts50 Nm (37 lb-ft)
7. 7

   Remove the strut assembly from the vehicle
   Lower the strut out of the tower and maneuver it down through the wheel well. Take care not to drag the strut against the stainless exoskeleton.
8. 8

   Replace the upper strut mount
   On a clean bench, mark the orientation of the upper mount relative to the strut body. If the strut uses a coil over an air spring, use a properly rated spring compressor before removing the top nut. For pure air-strut units, follow the manufacturer-specified disassembly sequence to remove the upper mount. Install the new manufacturer-specified upper mount in the same orientation. Torque the strut shaft top nut to OEM specification — refer to Tesla Service Manual.
   ⚠️If a coil spring is present, an improperly used spring compressor can release with lethal force. Use only a rated compressor and verify full engagement before loosening the top nut.

Reassembly

1. Install the strut assembly back into the tower, aligning the upper mount studs with the tower holes.
2. Hand-thread the strut tower nuts and torque to spec.
3. Raise the lower control arm with the jack to align the strut to the knuckle. Install the strut-to-knuckle bolts and torque to spec.
4. Reattach the sway bar end link and torque the nut while holding the stud with a hex key.
5. Reconnect the wheel speed sensor and any other harnesses; reseat them in their original clips.
6. Reconnect the air suspension line to the strut, ensuring the fitting is fully seated and the retainer is locked.
7. Reinstall the wheel and snug the lug nuts.
8. Lower the vehicle so full weight is on the wheels, then final-torque the wheel lug nuts and the lower control arm pivot bolts (control arm bolts MUST be torqued at ride height to avoid premature bushing failure).
9. Reconnect the 48V low-voltage battery.
10. Exit Service Mode. Allow the air suspension to re-pressurize and self-level; verify there are no air leaks (listen for hissing, monitor ride height over 10–15 minutes).
11. Clear any suspension/steer-by-wire faults and perform any required recalibration via Tesla service tooling.

Verification

• Confirm no suspension, ABS, ride-height, or steer-by-wire DTCs are present after LV reconnection.
• Verify the air suspension reaches and holds the commanded ride height; measure left/right front fender-to-ground heights — they should be within Tesla's published tolerance.
• Road test at low speed first: listen for clunks over bumps (indicates loose upper mount or unseated strut), confirm steering centers correctly (steer-by-wire must self-center).
• Inspect the strut air line fitting for leaks after the truck has held pressure for at least 30 minutes.
• Schedule a four-wheel alignment — mandatory after any front strut service on Cybertruck.
• Note: Tesla markets 'no scheduled maintenance,' but brake fluid (every 2 years), cabin air filter (every 2 years), and drive unit gear oil (initial ~12,500 mi, then 25k–50k) are real service items. Use this lift opportunity to inspect those if due.
