Strut Bearing

Replace the upper strut bearing (strut mount bearing) on a 2024 Tesla Cybertruck Cyberbeast. This requires removing the front strut assembly and disassembling it under spring compression — a hazardous procedure that demands a quality spring compressor.

Warnings

Tools required

Parts

• Upper strut bearing / strut mount bearing assembly × 1 — Manufacturer-specified Cybertruck front strut bearing — refer to Tesla parts catalog
• Strut top mount (recommended replacement when bearing is replaced) × 1 — Manufacturer-specified Cybertruck front strut upper mount
• Dust boot / bump stop kit (inspect and replace if worn) × 1 — Manufacturer-specified

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 low-voltage battery. NOTE: The Cybertruck uses a 48V architecture — locate the correct 48V battery disconnect per Tesla service documentation. Connectors and fusing differ from 12V Teslas.
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. Place the vehicle in Jack Mode / Service Mode via the touchscreen before lifting to disable the air suspension self-leveling.
7. Chock the rear wheels.
8. Loosen the front wheel lug nuts while the vehicle is still on the ground.
9. Raise the front of the vehicle and support on jack stands rated for Cybertruck weight. Place stands on factory lift points only — do not lift on the exoskeleton sills without proper pucks.
10. Remove the front wheel(s) on the side(s) being serviced.
11. Protect surrounding stainless body panels with fender covers.

Procedure

1. 1

   Disconnect sway bar end link from strut
   Locate the sway bar end link where it attaches to the strut (or lower control arm, depending on configuration). Hold the ball stud with an Allen key and remove the nut. Swing the link out of the way.
   Torque spec

   Sway Bar Link61 Nm (45 lb-ft)
2. 2

   Disconnect any sensors / wiring routed on the strut
   The Cybertruck routes ride-height sensor linkages, ABS/wheel-speed wiring, and brake hose brackets in the strut/knuckle area. Carefully unclip these brackets and move harnesses aside. Do not stretch the ride-height sensor link — it is fragile and critical to air suspension calibration.
   ⚠A damaged ride-height sensor will require replacement and recalibration of the air suspension.
3. 3

   Support the lower control arm
   Place a floor jack under the lower control arm to support its weight. This keeps the suspension neutral and prevents the knuckle from dropping suddenly when the strut is removed.
4. 4

   Remove the strut-to-knuckle bolts
   Mark the orientation of the strut-to-knuckle bolts (camber may be set here). Remove the through-bolts securing the strut to the steering knuckle. These are typically very tight — use a breaker bar.
   Torque spec

   Strut-to-Knuckle Bolts122 Nm (90 lb-ft)
5. 5

   Remove the upper strut tower nuts
   Open the front trunk / access panel above the strut tower. Remove any covers protecting the upper strut mount studs. Support the strut from below, then remove the upper strut tower nuts. Do NOT remove the center shaft nut at this stage.
   ⚠The strut will drop free once the top nuts are removed — keep it supported.
   Torque spec

   Strut Tower Nuts50 Nm (37 lb-ft)
6. 6

   Remove the strut assembly from the vehicle
   Carefully maneuver the strut assembly down and out of the wheel well. Note its orientation for reinstallation.
7. 7

   Compress the coil spring
   Mount the strut securely. Install a heavy-duty spring compressor on the coil, ensuring the hooks are seated on at least 4-5 coils and clamped evenly on opposite sides. Compress slowly and uniformly until all tension is removed from the upper spring seat. Verify by attempting to rotate the upper seat by hand — it should turn freely.
   ⚠️Stand to the side, never in line with the spring. A slipped compressor can launch parts with lethal force.
8. 8

   Remove the center strut shaft nut
   Hold the strut shaft from rotating using the manufacturer-recommended counter-hold (typically a hex socket on the shaft tip with a wrench on the flats, or a strut nut tool). Loosen and remove the center nut.
9. 9

   Disassemble the upper strut stack
   Lift off, in order: the upper strut mount, the strut bearing (the part being replaced), the upper spring seat/isolator, and any dust boot/bump stop. Lay parts out in order on a clean surface.
10. 10

    Inspect and install the new strut bearing
    Compare new bearing to old — ensure correct orientation (bearings are directional). Inspect the upper mount for cracking or rubber separation; replace if any doubt. Inspect the bump stop and dust boot. Lightly grease the bearing only if specified by the bearing manufacturer (most modern sealed bearings do not require additional grease).
11. 11

    Reassemble the strut stack
    Reinstall components in reverse order, ensuring the spring's lower coil is seated correctly in the lower perch indexing pocket and the upper seat indexes correctly to the spring end. Install the center shaft nut and torque to OEM specification — refer to Tesla Service Manual.
    ⚠Improper spring indexing will cause uneven ride height and accelerated bearing failure.
12. 12

    Slowly release the spring compressor
    Release the compressor evenly on both sides, watching the spring as it expands to confirm it seats correctly in both perches. Once fully released, remove the compressor.

Reassembly

1. Maneuver the strut assembly back into position. Align the upper studs through the strut tower holes first, then guide the lower end into the knuckle.
2. Hand-thread the upper strut tower nuts to hold the assembly in place.
3. Insert the strut-to-knuckle through-bolts in the marked orientation. Hand-tighten only at this stage.
4. Torque the upper strut tower nuts to spec.
5. Reconnect the sway bar end link, holding the ball stud with an Allen key while torquing the nut.
6. Reinstall the ride-height sensor linkage, ABS wiring, and brake hose brackets exactly as removed.
7. Reinstall the wheel and snug the lug nuts.
8. Lower the vehicle so full weight is on the wheels.
9. With the vehicle at normal ride height, torque the strut-to-knuckle bolts and any control arm bolts that were disturbed. Control arm bolts MUST be torqued at ride height to avoid pre-loading the bushings.
10. Torque the wheel lug nuts in a star pattern.
11. Reconnect the 48V low-voltage battery.
12. Exit Jack Mode / Service Mode via the touchscreen and allow the air suspension to re-level.
13. Cycle the suspension through all height settings to verify proper operation.

Verification

• Confirm no warning messages on the touchscreen related to suspension, steering, or ride height after wake-up.
• Verify the air suspension levels properly at all four corners and that side-to-side ride height is even (within Tesla spec).
• Test drive at low speed in a safe area: listen for clunks, popping, or grinding from the strut tower when turning lock-to-lock — a noisy strut bearing was likely the original symptom and should now be gone.
• Inspect strut tower area for any leaks or loose fasteners after the test drive.
• Have a four-wheel alignment performed — Cybertruck alignment is sensitive due to its weight and steer-by-wire calibration.
• If the steering feel is off-center or the touchscreen shows a steering-related fault, the steer-by-wire system may require a steering angle relearn via Tesla service tooling.
• While the vehicle is in the air, this is also a good time to inspect brake fluid condition (Tesla recommends replacement every 2 years) and cabin air filter age (every 2 years) since the front trunk area is already accessed.
