Replace the front upper control arm bushing on a 2024 Tesla Cybertruck Dual Motor. On this platform the front upper control arm is part of a multi-link air-suspension setup; in many cases Tesla supplies the upper arm as an assembly, so confirm bushing serviceability before ordering parts.
Warnings
⚠️Cybertruck uses a 48V low-voltage system — NOT 12V. Standard 12V tools/jumpers can damage the LV system. Disconnect at the 48V LV battery only.
⚠️Do not touch, cut, or pierce any orange cable. The Cybertruck HV system is 800V — substantially more lethal than earlier Tesla 400V packs.
⚠️Air suspension: the system can self-level or vent unexpectedly. Place the vehicle in Jack/Service Mode via the touchscreen before lifting, and never work under a vehicle supported only by the air springs.
⚠Steer-by-wire: there is no mechanical steering column linkage. Do not attempt to 'feel' steering via the yoke while suspension is disassembled — the front wheels can move independently when the system is powered.
⚠Stainless exoskeleton panels are structural and easily marred. Do not strike with steel hammers; protect fender edges when working in the wheel well.
⚠Cybertruck curb weight exceeds 6,600 lb. Use jack stands and lift arms rated accordingly — typical passenger car stands are insufficient.
ℹ️An alignment is required after any control arm service. Mark cam bolt positions before removal to get close, but a four-wheel alignment on a rack capable of accommodating the Cybertruck's wheelbase and ride-height settings is mandatory.

Parts
- Front upper control arm bushing (verify Tesla sells separately; otherwise full upper control arm assembly) × 1 — Manufacturer-specified Cybertruck front upper control arm bushing or assembly
- Ball joint cotter pin × 1 — OEM cotter pin matching ball joint stud
- Control arm pivot bolts (replace if single-use — verify in service manual) × 2 — Manufacturer-specified bolts
Preparation
- Park on level ground, place in P, engage parking brake.
- 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.
- Disconnect the 48V low-voltage battery (Cybertruck uses 48V LV architecture, not 12V). Refer to the Tesla Service Manual for the LV battery location and disconnect sequence specific to Cybertruck.
- DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal on this 800V platform.
- 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: enter Service Mode / Jack Mode on the touchscreen to disable the air suspension self-leveling and vent reservoir pressure per on-screen prompts.
- Loosen front wheel lug nuts while the truck is on the ground.
- Lift the vehicle on a hoist or stands rated for Cybertruck weight; allow the front suspension to hang or support the lower control arm with a jack as required by the procedure.
- Remove the front wheel on the affected side.
Procedure
- 1Document and mark alignment referencesBefore loosening anything, mark the position of any cam/eccentric bolts at the upper control arm pivots with a paint pen. Photograph the routing of any wiring harnesses or air suspension lines that pass near the upper arm. This shortens the post-repair alignment and prevents pinched lines.
- 2Access the upper control armRemove the front wheel well liner fasteners as needed for access to the upper arm and ball joint. Tuck or unclip any wheel-speed sensor harnesses, ride-height sensor links, or air lines that route along the upper arm. Do not stretch or kink air suspension lines.⚠Air suspension lines are nylon/composite — a sharp kink can cause a slow leak that is difficult to diagnose later.
- 3Support the knuckle / lower armPlace a jack with a wood block under the lower control arm or steering knuckle to support the corner. This relieves spring/strut load from the upper ball joint and prevents the knuckle from dropping when the upper joint is separated.
- 4Disconnect the upper ball joint from the knuckleRemove and discard the cotter pin from the upper ball joint nut. Loosen and remove the ball joint nut. Separate the ball joint stud from the knuckle using a proper ball joint separator; avoid pickle-fork tools that can damage the boot if the joint is being reused.⚠Do not strike the aluminum knuckle with a steel hammer to free the taper. Use a separator tool.Torque specBall Joint Nut88 Nm (65 lb-ft)
- 5Remove the upper control arm pivot boltsSupport the upper control arm. Remove the inboard pivot bolts/nuts securing the upper arm to the frame/subframe brackets. Note the orientation of any cam washers and the direction the bolts are installed (some chassis bolts must be driven in from a specific side for clearance).Torque specControl Arm Bolts165 Nm (122 lb-ft)
- 6Remove the upper control arm from the vehicleManeuver the upper arm out of the chassis. Inspect the arm itself, the ball joint boot, and the mounting brackets for damage, cracks, or corrosion before proceeding.ℹ️If the bushing is not serviceable as a separate part on this Cybertruck arm, the entire upper control arm assembly must be replaced. Verify before pressing.
- 7Press out the old bushingIf the bushing is replaceable, secure the upper arm in a press with appropriate cradle/receiver adapters. Press the old bushing out in the manufacturer-specified direction. Do not heat the arm with an open flame — many modern Tesla suspension arms are forged or cast aluminum and will lose temper.⚠Never apply press force directly on the control arm body — always through the bushing outer sleeve via a proper adapter.
- 8Install the new bushingLubricate the outer sleeve only with the lubricant specified by the bushing manufacturer (typically a soap-based assembly lube — never petroleum grease on rubber bushings). Press the new bushing in squarely until it is fully seated to the depth specified by the service manual. Confirm the bushing is not cocked.
- 9Reinstall the upper control armPosition the arm in its brackets and insert the pivot bolts in the original orientation, including any cam washers aligned to your reference marks. Start nuts by hand; do NOT final-torque the pivot bolts yet — they must be torqued at ride height.⚠Torquing rubber-bonded bushing pivots while the suspension hangs will preload the bushing and cause premature failure.
- 10Reconnect the upper ball jointSeat the ball joint stud into the knuckle. Install the ball joint nut and torque to specification. Install a NEW cotter pin; if the slot does not align, tighten further (never loosen) until it does.Torque specBall Joint Nut88 Nm (65 lb-ft)
- 11Reinstall harnesses, liner, and wheelReroute any wheel-speed sensor harness, ride-height sensor link, and air lines exactly as photographed. Reinstall the wheel well liner. Mount the wheel and snug the lug nuts.
- 12Lower vehicle and final-torque pivot bolts at ride heightLower the vehicle so full vehicle weight is on the wheels (or simulate ride height with the suspension loaded on a drive-on lift). With the suspension at normal ride height, torque the upper control arm pivot bolts to specification. Then final-torque the wheel lug nuts in a star pattern.⚠Cybertruck air suspension may need to be exited from Jack Mode and allowed to relevel before bushings see true ride-height load.Torque specControl Arm Bolts165 Nm (122 lb-ft)Wheel Lug Nuts136 Nm (100 lb-ft)
Reassembly
- Reconnect the 48V low-voltage battery using Cybertruck-specific reconnect procedure.
- Exit Jack/Service Mode on the touchscreen and allow the air suspension to fully relevel.
- Cycle the suspension through ride-height settings (if user-selectable) to confirm the system pressurizes correctly with no leaks at moved/disturbed lines.
- Inspect for any warning messages related to suspension, ride height, or steer-by-wire on the center display.
Verification
- Perform a four-wheel alignment on an alignment rack capable of supporting Cybertruck weight and reading its ride-height-dependent specs. This is mandatory after any upper control arm disturbance.
- Test drive at low speed first, listening for clunks from the upper arm area on bumps and during steering input — remember that on steer-by-wire there is no mechanical feedback, so audible/visual cues are your primary diagnostic.
- Recheck the area for air-line leaks — listen for hiss with the truck at full ride height, and verify no 'Air Suspension Fault' or 'Ride Height' warnings appear after a heat cycle.
- Re-torque wheel lug nuts after approximately 80–160 km (50–100 mi) of driving.
- Note: while doing front suspension work is a good time to inspect items that Tesla quietly recommends despite the 'no scheduled maintenance' marketing — including brake fluid (2-year service), cabin air filter (2-year service), and drive unit gear oil at the recommended Tesla intervals.
