Replace the front wheel bearing/hub assembly on a 2024 Model Y Performance AWD. The hub is a unitized pressed-in bearing bolted to the steering knuckle from behind — no press required if you remove the four hub bolts cleanly.

Warnings

Tools required

Parts

• Front Wheel Bearing Hub Assembly (Model Y Performance, 2024) × 1 — Tesla-spec front hub assembly — confirm with VIN
• Axle nut (single-use) × 1 — OEM single-use stake nut or castellated nut with cotter pin
• Cotter pin (if applicable) × 1 — Match OEM size

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 12V low-voltage battery (located under the rear seat or in the front trunk area depending on build — refer to in-vehicle service mode for exact location on this 2024 build).
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 Service Mode via the touchscreen if 12V was reconnected for any reason — this disables regen and prevents motor activation.
7. Loosen front wheel lug nuts while the wheel is on the ground.
8. Loosen the axle nut (staked or cotter-pinned) while the wheel is still on the ground — this requires significant torque to break loose.
9. Raise the front of the vehicle at the manufacturer-specified jack points (reinforced pucks under the pinch welds) and support on jack stands rated for the vehicle weight.

Procedure

1. 1

   Remove front wheel
   Remove the lug nuts and pull the wheel straight off. Set aside on the tire face to protect the finish.
2. 2

   Remove brake caliper and caliper bracket
   Remove the two caliper guide pin bolts and lift the caliper off the rotor. Suspend it from the coil spring or strut with wire — do not let it hang by the brake hose. Then remove the two caliper bracket bolts from the knuckle and set the bracket aside.
   ⚠Never let the caliper hang by the flexible brake hose — internal damage can cause hose failure.
3. 3

   Remove brake rotor
   Remove the small retaining screw if present and pull the rotor off the hub. If seized, apply penetrating oil to the hub center and tap evenly with a dead-blow hammer.
4. 4

   Disconnect ABS sensor
   Remove the bolt securing the ABS/wheel speed sensor to the knuckle and carefully extract the sensor. Set it aside out of the work area — do not pull on the wiring.
   ⚠ABS sensors can seize in the knuckle. Do not pry on the sensor body — apply penetrating oil and twist to release.

   ABS Sensor Bolt10 Nm (7 lb-ft)
5. 5

   Remove axle nut and separate axle from hub
   Remove the cotter pin (if equipped) and fully remove the axle nut that was loosened during prep. Push the outer CV stub axle inward to free it from the hub splines. If seized, use a hub puller — do not hammer the axle threads.
   ⚠Do not hang the half-shaft by the inner CV joint. Support it with wire to the chassis.
6. 6

   Access and remove hub assembly bolts
   From behind the steering knuckle, locate the four hub mounting bolts. Note their orientation. Remove all four bolts. The hub assembly will then be free to pull forward out of the knuckle.
   ⚠Hub bolts are typically installed with threadlocker and may require significant force to break free. Use a properly fitting bit to avoid stripping.
   Torque spec

   Wheel Bearing Hub Bolts110 Nm (81 lb-ft)
7. 7

   Remove old hub assembly
   Pull the hub assembly forward out of the knuckle bore. If corroded in place, use a slide hammer or carefully tap from the rear with a brass drift. Inspect the knuckle bore for corrosion and clean thoroughly with a wire brush.
   ⚠Aluminum knuckle — do not strike directly with a steel hammer. Use brass drifts only and tap evenly.
8. 8

   Prepare and install new hub assembly
   Apply a light film of anti-seize to the hub-to-knuckle mating surface (not on the bolt threads). Position the new hub onto the knuckle, ensuring the ABS tone ring (if integrated) faces the correct direction. Apply medium-strength threadlocker to the hub bolt threads if specified by the OEM.
9. 9

   Torque new hub bolts
   Install the four hub bolts hand-tight, then torque in a cross pattern to the specified value. Verify all four bolts reach final torque.

    Reinstall axle through hub
    Guide the outer CV stub axle splines through the new hub. Install a NEW axle nut — never reuse the original. Snug the nut but do not final-torque until the wheel is back on the ground.
    ⚠The axle nut is single-use. Reusing it can cause it to back off in service.
11. 11

    Reinstall ABS sensor
    Clean the sensor bore in the knuckle. Apply a small amount of dielectric grease to the sensor O-ring. Insert the sensor fully and torque the retaining bolt.

12. 12

    Reinstall rotor, caliper bracket, and caliper
    Install the rotor and retaining screw if equipped. Install the caliper bracket with threadlocker on the bolts and torque to spec. Reinstall the caliper over the rotor and torque the guide pin bolts to OEM specification.
    ℹ️Pump the brake pedal several times before driving to reseat the caliper pistons against the new rotor.

Reassembly

1. Reinstall the front wheel and snug the lug nuts in a star pattern.
2. Lower the vehicle to the ground.
3. Final-torque the wheel lug nuts in a star pattern to specification.
4. Final-torque the axle nut to specification with the vehicle on the ground (use an assistant on the brake pedal to prevent rotation).
5. Install a new cotter pin or stake the new axle nut per OEM design.
6. Reconnect the 12V battery.
7. Pump the brake pedal firmly several times until it feels solid before moving the vehicle.

Verification

• Exit Service Mode via the touchscreen and verify no ABS, traction control, or stability control warning lights remain on the driver display.
• With the vehicle stationary, turn the steering lock-to-lock and listen for any grinding, clicking, or rubbing from the hub area.
• Test drive at low speed (5-15 mph) in an empty area and listen for bearing noise or ABS faults. Any humming or growling that changes with steering input indicates an installation problem.
• Test drive at 30-50 mph and verify no vibration, no pulling, and no warning lights.
• Recheck axle nut torque after the first 100 miles — critical safety item.
• Tesla recommends a front-end alignment check after any front suspension or hub service. Given the Model Y's aggressive tire wear pattern, an alignment is strongly advised.
• While the vehicle is up, note next service intervals: tire rotation every 6,250 mi, brake fluid every 2 years, cabin filter every 2 years.
