Wheel Bearing Hub - Rear

Replace the rear wheel bearing hub assembly on a 2024 Tesla Cybertruck Dual Motor AWD. The Cybertruck uses a pressed/bolted hub design integrated with the rear knuckle and air suspension — work carefully around the 48V low-voltage harness and ABS/wheel speed sensor wiring.

Warnings

Tools required

Parts

• Rear wheel bearing hub assembly (Cybertruck-specific) × 1 — Tesla OEM rear hub assembly — verify part number against VIN at parts.tesla.com
• Axle nut (single-use; replace if specified by OEM) × 1 — OEM single-use axle nut per Tesla Service Manual
• Hub mounting bolts (replace if specified as single-use) × 4 — OEM hub-to-knuckle bolts

Preparation

1. Park on level ground, place in P, engage 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. Disconnect the 48V low-voltage battery using insulated tools and 48V-rated gloves. Note: Cybertruck's LV battery is 48V — NOT 12V like other Teslas. Refer to Tesla Service Manual for exact LV battery location and disconnect sequence.
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. Engage Jack Mode / Service Mode via the touchscreen to disable air suspension auto-leveling before lifting.
7. Loosen rear wheel lug nuts while the vehicle is on the ground.
8. Lift the rear of the vehicle at manufacturer-specified jack points and support on rated jack stands.
9. Remove the rear wheel.

Procedure

1. 1

   Remove rear brake caliper
   Disconnect or unclip the brake pad wear sensor wiring (if equipped) from the caliper. Remove the two caliper bracket bolts securing the caliper assembly to the rear knuckle. Support the caliper with a bungee cord or hanger — DO NOT let it hang by the flexible brake hose. Set aside without disconnecting hydraulic lines.
   ⚠Do not press the brake pedal while the caliper is removed — this can extend the piston and damage the seal.
2. 2

   Remove brake rotor
   Remove any rotor retaining clip or set screw if present. Slide the rear brake rotor off the hub. If corroded in place, apply penetrating oil to the hub-rotor interface and use a soft mallet — do not strike with a steel hammer.
3. 3

   Disconnect ABS / wheel speed sensor
   Locate the ABS wheel speed sensor on the rear knuckle. Unclip the harness from any retaining clips along the trailing arm. Remove the ABS sensor bolt and carefully extract the sensor from the knuckle. Set aside where it cannot be damaged.
   ⚠ABS sensors are fragile. Do not pry on the sensor body — twist gently to free it from the bore.
4. 4

   Loosen and remove axle nut
   With an assistant pressing the brake pedal (or wheel reinstalled and on ground), break loose the rear axle nut using a breaker bar and the correct-size socket. The axle nut torque is very high (200 Nm installed). Remove the axle nut completely once the wheel is off the ground again.
   ⚠The axle nut may be staked or single-use. Inspect for staking/deformation and replace per OEM specification.
   Torque spec

   Axle Nut200 Nm (148 lb-ft)
5. 5

   Separate halfshaft from hub
   Push the halfshaft (CV axle) splined stub inward through the hub. If seized, use a soft-faced punch and gentle taps, or a hub puller. Support the halfshaft so it does not hang from the inner CV joint. If clearance is insufficient, you may need to unbolt the inner CV joint flange from the differential output flange — refer to CV Joint Bolts torque if reinstalling.
   ⚠Do not allow the halfshaft to hang by the inner joint — this can damage the CV cage and boot.
6. 6

   Remove hub assembly mounting bolts
   From the back side of the rear knuckle, locate the hub bearing mounting bolts (typically 4) securing the hub assembly to the knuckle. Remove each bolt. Note orientation and any spacers, dust shields, or backing plates.
   Torque spec

   Wheel Bearing Hub Bolts100 Nm (74 lb-ft)
7. 7

   Extract old hub assembly
   Pull the hub assembly forward out of the knuckle bore. If corroded in place, use a slide hammer with a hub puller adapter. Avoid prying against the knuckle face with steel tools — protect mating surfaces. Inspect the knuckle bore for corrosion or scoring.
8. 8

   Clean and inspect mating surfaces
   Thoroughly wire-brush the knuckle bore and bolt threads. Remove all corrosion and old threadlocker residue. Inspect the knuckle for cracks, elongated bolt holes, or damage. Inspect the halfshaft splines for wear or twisting damage.
9. 9

   Install new hub assembly
   Position the new wheel bearing hub assembly into the knuckle bore, aligning the bolt holes and any backing plate / dust shield. Apply medium-strength threadlocker to the hub mounting bolts if specified. Install bolts hand-tight first, then torque in a star pattern to specification.
   ℹ️Tighten in a star/cross pattern in two stages to seat the hub squarely against the knuckle face.

10. 10

    Reinstall halfshaft and axle nut
    Slide the halfshaft splines through the new hub. Install the axle nut (new, if single-use). Hand-thread first, then torque to specification once the wheel is reinstalled and on the ground (or with a brake-hold assistant). Stake the nut if the OEM design requires staking.

11. 11

    Reinstall ABS sensor
    Clean the ABS sensor bore and sensor tip. Insert the sensor fully into the knuckle and secure with the retaining bolt. Reroute the harness through all original clips to prevent contact with rotating components.
12. 12

    Reinstall brake rotor and caliper
    Slide the brake rotor onto the new hub. Reinstall the caliper bracket assembly over the rotor and torque the caliper bracket bolts to specification with threadlocker applied. Reconnect any wear sensor harness.

Reassembly

1. Reinstall the rear wheel and hand-thread lug nuts.
2. Lower the vehicle until the tire just contacts the ground, then torque the axle nut to 200 Nm (148 lb-ft).
3. Lower fully and torque the wheel lug nuts to 175 Nm (129 lb-ft) in a star pattern.
4. Reconnect the 48V low-voltage battery using insulated tools.
5. Exit Service/Jack Mode via the touchscreen and allow the air suspension to re-level.
6. Pump the brake pedal several times to restore caliper piston pressure before driving.

Verification

• With the vehicle running, confirm no ABS, traction control, or stability control warnings appear on the touchscreen. The Cybertruck may require a short drive cycle to clear stored faults.
• Listen for bearing noise (growl/hum) at 25-45 mph that changes with steering load — indicates improper seating or damaged bearing.
• Verify no brake pull or pulsation on a test drive.
• Recheck wheel lug torque after 50-100 miles of driving — Cybertruck's mass accelerates lug seating.
• Confirm air suspension self-levels correctly at all four corners.
• Scan for stored DTCs using a compatible OBD tool. Note: full Cybertruck diagnostic clearing may require Tesla Service — if persistent codes appear, consult a Tesla-certified technician.
• While the vehicle is up, this is a good opportunity to inspect rear differential fluid (Tesla now recommends drive unit fluid service at 12,500 mi initially, then every 25,000-50,000 mi — not 'lifetime' as historically marketed).
