Replace the front lower control arm bushing on a 2024 Tesla Cybertruck Cyberbeast. Due to the integrated nature of the Cybertruck's forged aluminum front lower control arm, bushing replacement typically requires removing the control arm and pressing the bushing in/out, or replacing the arm assembly if bushings are not serviced separately.
Warnings
⚠️This Cybertruck uses a 48V low-voltage system — NOT 12V. Use only 48V-rated tools/fuses and follow Tesla's 48V LV disconnect procedure. Do not assume 12V Model 3/Y procedures apply.
⚠️Steer-by-wire: there is NO mechanical link between the yoke and the front wheels. Do not rotate the steering rack manually with the LV system disconnected — this can cause calibration faults requiring Tesla service software.
⚠️If you see ANY orange cable in the work area, STOP. The Cybertruck uses an 800V HV architecture — contact is lethal.
⚠Stainless steel exoskeleton: do not strike body panels or use them as pry points. Damage cannot be repaired with conventional bodywork.
⚠Air suspension: the vehicle may auto-level or attempt to adjust ride height. Place the vehicle in Jack/Service Mode via the touchscreen BEFORE lifting to disable air suspension self-leveling.
⚠Cybertruck curb weight is ~6,600-6,900 lb. Use jack stands and lift points rated accordingly. Use only Tesla-designated lift points to avoid crushing the battery enclosure.
ℹ️Final torque on control arm pivot bolts MUST be applied with suspension loaded at ride height — torquing at full droop will pre-load the bushing and cause premature failure.
Tools required

Metric Allen/hex key set (for sway bar end link shafts)Essential
Ball joint separator / pickle fork or tie rod pullerEssential
Hydraulic press or bushing service kit (for pressing new bushing)Essential
Cotter pin assortmentEssential
Pry bar
Suspension support stand or secondary jack (to load arm for final torque)Essential
Insulated gloves (1000V rated) for LV battery disconnect
Parts
- Front lower control arm bushing (manufacturer-specified) × 1 — Refer to Tesla EPC for Cybertruck Tri Motor front LCA bushing — verify if serviced separately or arm-only
- Ball joint cotter pin (single-use) × 1 — OEM-spec cotter pin
- Control arm pivot bolts (inspect; replace if TTY — verify with service manual) × 2 — OEM-spec, verify reuse policy
Preparation
- Park on level ground, place in P, engage parking brake.
- 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.
- Disconnect the 48V low-voltage battery per Tesla Cybertruck service procedure (location and connector style differ from 12V Teslas — refer to service manual).
- DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage (800V) and lethal.
- 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.
- Before lifting: enable Jack Mode / Service Mode on the touchscreen to lock out air suspension self-leveling.
- Loosen front wheel lug nuts while vehicle is on the ground.
- Lift vehicle at OEM-specified front lift points and support on rated jack stands. Confirm stable before going underneath.
- Remove front wheel on the affected side.
Procedure
- 1Inspect and photographPhotograph the front suspension assembly from multiple angles before disassembly. Note bushing orientation, alignment marks, and any shims. Inspect for corrosion or damage that may complicate removal.
- 2Disconnect sway bar end linkAt the lower control arm, remove the sway bar end link nut. Hold the end link shaft with an Allen key to prevent spinning. Swing the link out of the way.Torque specSway Bar Link Nuts55 Nm (41 lb-ft)
- 3Separate lower ball jointRemove the cotter pin from the lower ball joint stud, then loosen (but do not fully remove) the ball joint nut. Use a ball joint separator to break the taper. Once free, fully remove the nut and separate the knuckle from the lower control arm. Support the knuckle with a strap or stand — do NOT let it hang on the half-shaft or brake hose.⚠Discard the cotter pin — single-use only. A new one is required on reassembly.Torque specBall Joint Nut88 Nm (65 lb-ft)
- 4Support and mark control armPlace a jack under the lower control arm to support its weight. Mark the position of any cam/eccentric bolts at the inboard pivots so original alignment can be approximated on reinstall.ℹ️A four-wheel alignment will still be required after this job — Cybertruck alignment is sensitive due to steer-by-wire calibration.
- 5Remove inboard control arm pivot boltsRemove the inboard control arm pivot bolt(s) at the subframe. Lower the jack slowly to let the arm drop free. Remove the control arm from the vehicle.Torque specControl Arm Bolts165 Nm (122 lb-ft)
- 6Press out old bushingMount the control arm in a press or use a bushing service kit. Press the worn bushing out using the manufacturer-specified adapter. Verify the bushing housing/eye is clean and undamaged. If the bushing is not serviced separately by Tesla for the Cybertruck, the entire control arm must be replaced as an assembly — verify before pressing.⚠Do NOT heat aluminum control arm components with a torch to free a stuck bushing — this anneals the aluminum and compromises structural integrity.
- 7Press in new bushingLubricate the bushing housing per the bushing manufacturer's instructions (typically only the outer steel sleeve, not the rubber). Press the new bushing in squarely to the OEM-specified depth and clocking orientation. Verify final position matches the removed bushing.
- 8Reinstall control arm to subframePosition the control arm at the subframe and install the inboard pivot bolt(s) hand-tight. Do NOT final-torque yet — the bushing must be torqued at ride height to avoid pre-loading.
- 9Reconnect ball jointReconnect the lower ball joint stud to the steering knuckle. Install a NEW castle nut (or reuse per service manual guidance) and torque to specification. Continue tightening (do not loosen) to align the next slot with the cotter pin hole. Install a NEW cotter pin and bend per OEM pattern.⚠️If torque spec is reached and slot does not align, tighten further to next slot — NEVER back off the nut. Backing off can cause ball joint separation and loss of steering control.Torque specBall Joint Nut88 Nm (65 lb-ft)
- 10Reinstall sway bar end linkReconnect the sway bar end link to the control arm. Hold the link's shaft with an Allen key while torquing the nut.Torque specSway Bar Link Nuts55 Nm (41 lb-ft)
Reassembly
- Reinstall the front wheel; snug lug nuts in a star pattern.
- Lower the vehicle until the suspension is loaded at normal ride height (tires fully on the ground or on alignment-rated drive-on supports).
- With suspension loaded, final-torque the inboard control arm pivot bolts to 165 Nm (122 lb-ft).
- Torque wheel lug nuts in a star pattern to 136 Nm (100 lb-ft).
- Reconnect the 48V low-voltage battery per Tesla procedure.
- Exit Jack/Service Mode on the touchscreen and allow air suspension to self-level.
- Cycle the vehicle through Drive/Reverse at low speed in a safe area to verify steer-by-wire calibration is normal — if any steering fault appears on the touchscreen, stop and have the system serviced.
Verification
- Confirm no suspension or steering fault messages on the Cybertruck touchscreen after reconnecting LV power.
- Inspect cotter pin installation on the ball joint — must be fully seated and bent per OEM pattern.
- Verify air suspension self-levels to normal ride height with no leak-down over 30 minutes.
- Road test at low speed first, listening for clunks over bumps; bushing pre-load issues will manifest as a binding or 'memory steer' feel.
- Schedule a four-wheel alignment immediately — front camber/caster on Cybertruck is highly sensitive, and steer-by-wire requires correct geometry for proper feedback calibration.
- Note: while in this area, this is a good time to inspect the cabin air filter (Tesla recommends replacement every 2 years) and verify brake fluid age (Tesla recommends 2-year service interval regardless of mileage).
