Wheel Bearing Hub - Rear

Replacement of a rear wheel bearing/hub assembly on the 2024 Tesla Cybertruck Cyberbeast Tri Motor. The rear hub is bolted to the rear knuckle and retains the outer CV stub via a single high-torque axle nut; air suspension and steer-by-wire do not directly affect this job, but special care is required around the 48V LV system and the stainless exoskeleton.

Warnings

Tools required

Parts

• Rear wheel bearing/hub assembly (manufacturer-specified for Cybertruck Tri Motor) × 1 — OEM Tesla Cybertruck rear hub assembly — refer to Tesla EPC
• Axle nut (single-use; replace if specified by Tesla) × 1 — OEM-specified single-use axle nut
• Hub mounting bolts (replace if specified) × 4 — OEM-specified hub bolts

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 48V low-voltage battery per Tesla's documented procedure for Cybertruck (location differs from 12V Teslas — refer to Service Manual).
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 air suspension in Jack Mode / Service Mode via the touchscreen BEFORE lifting; this prevents the system from auto-leveling and damaging components.
7. Loosen rear wheel lug nuts while the vehicle is still on the ground.
8. Lift the rear of the vehicle at the manufacturer-specified lift points and support on rated jack stands.
9. Remove the rear wheel and set aside on a soft surface to protect the finish.

Procedure

1. 1

   Remove the axle nut
   With the wheel removed, have an assistant apply the brake (or reinstall two lug nuts and wedge a pry bar) to keep the hub from spinning. Remove the staking/cap if present, then break loose and remove the rear axle nut from the outer CV stub. Discard if Tesla specifies single-use.
   ⚠Axle nut is high-torque; use a long breaker bar or impact. Do not use the brake caliper as a holding device.
   Torque spec

   Axle Nut200 Nm (148 lb-ft)
2. 2

   Remove the brake caliper and bracket
   Remove the caliper guide pin bolts and slide the caliper off the rotor. Support it with a hanger — never let it hang by the flexible brake hose. Then remove the rear caliper bracket bolts and set the bracket aside.
   ⚠Do not stretch the flexible brake line. Suspend the caliper from a suspension component using a hanger or bungee.
3. 3

   Remove the brake rotor
   Remove any retaining clip or set screw if present and pull the rear rotor off the hub. If corroded in place, thread bolts into the rotor's puller-holes (if equipped) to push it free. Do not strike with a steel hammer near the exoskeleton.
4. 4

   Disconnect the ABS/wheel speed sensor
   Trace the ABS sensor harness from the knuckle, release any retaining clips, and remove the ABS sensor bolt. Carefully pull the sensor from the knuckle — twist gently if seized. Move the harness aside so it is not damaged during hub removal.
   ⚠Do not pull on the ABS harness. The sensor tip is fragile and easily broken if pried with a screwdriver.
5. 5

   Free the outer CV stub from the hub
   Push the outer CV joint stub axle inward through the hub splines. If it is seized, apply penetrating oil and use a soft-faced punch on the stub end (never on the threads). The half-shaft does not need to be fully removed unless required for hub clearance.
   ⚠Do not let the half-shaft hang by the inner CV joint — support it to prevent damage to the inboard joint and seal.
6. 6

   Remove the hub assembly mounting bolts
   From behind the knuckle, remove the four wheel bearing hub bolts retaining the hub assembly to the rear knuckle. Note bolt orientation. Discard if Tesla specifies single-use.
   Torque spec

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

   Remove the hub assembly from the knuckle
   Pull the hub assembly forward off the knuckle and over the CV stub. If corroded in place, use a slide hammer or hub puller — do not pry against the knuckle face or strike the exoskeleton. Clean the knuckle's hub mating bore with a wire brush; remove all rust and debris so the new hub seats flush.
   ⚠An improperly cleaned mating surface will cause the new hub to sit cocked, leading to premature bearing failure and possible ABS tone-ring runout.

Reassembly

1. Apply a light film of anti-seize to the hub-to-knuckle mating surface (not the bolt threads, not the bearing face).
2. Position the new hub assembly onto the knuckle, aligning over the CV stub splines. Confirm the ABS tone ring (if integrated) is oriented correctly.
3. Install the hub mounting bolts. Apply threadlocker if specified by Tesla. Tighten in a cross pattern to the Wheel Bearing Hub Bolts spec (100 Nm / 74 lb-ft).
4. Reinstall the ABS wheel speed sensor and torque the ABS Sensor Bolt to 11 Nm (8 lb-ft). Reseat the harness in its original clips.
5. Install a new axle nut on the CV stub. With the brake reapplied, torque the Axle Nut to 200 Nm (148 lb-ft). Stake the nut if Tesla's design requires it.
6. Reinstall the brake rotor.
7. Reinstall the caliper bracket with threadlocker; torque Caliper Bracket Bolts - Rear to 100 Nm (74 lb-ft).
8. Reinstall the caliper and torque guide pin bolts to OEM specification — refer to Tesla Service Manual.
9. Reinstall the wheel and snug the lug nuts.
10. Lower the vehicle to the ground and torque Wheel Lug Nuts to 175 Nm (129 lb-ft) in a star pattern.
11. Reconnect the 48V low-voltage battery per Tesla procedure.
12. Exit Jack/Service mode on the touchscreen and allow the air suspension to re-level.

Verification

• Power the vehicle on with the door closed and key present. Verify no ABS, traction control, stability control, or ride-height warnings remain on the instrument cluster after a 5–10 minute drive cycle.
• With wheels off the ground, spin the rear wheel by hand and listen for grinding, roughness, or play in the new bearing.
• Check for excessive runout by mounting a dial indicator on the rotor face — Cybertruck's regen braking is sensitive to runout and may telegraph as pulsation.
• Road test at low speed first, listening for hum or growl that changes with cornering load (indicates incorrect preload or contaminated bearing).
• Recheck Wheel Lug Nut torque after the first 50–100 miles.
• Note: rear differential gear oil is not 'lifetime' — if mileage is approaching Tesla's recommended 12,500 mi initial service or 25,000–50,000 mi interval, advise the owner to schedule that service.
