Replace a rear wheel bearing/hub assembly on a 2024 Model Y Performance AWD. The rear hub is bolted to the knuckle and retains the half-shaft via a staked axle nut.

Warnings

Tools required

Parts

• Rear wheel bearing/hub assembly × 1 — Tesla Model Y rear hub assembly — refer to OEM specification
• Axle nut (single-use, replace with new) × 1 — OEM staked/prevailing-torque axle nut
• Hub mounting bolts (replace if specified by OEM) × 4 — OEM rear hub 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 12V low-voltage battery. On 2024 Model Y, the 12V (Li-ion) battery is accessed under the rear seat / cargo area trim — refer to vehicle for exact location.
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 Transport/Jack Mode via the touchscreen (Service menu) before lifting to disable air-suspension self-leveling logic and ride-height changes (note: Model Y uses coil suspension, but Jack Mode also disables certain park/brake auto-engage behaviors).
7. Loosen the rear wheel lug nuts while the wheel is still on the ground.
8. With weight still on the wheel, un-stake and break loose the rear axle nut (it is torqued very high — do not attempt with the wheel in the air).

Procedure

1. 1

   Lift and support the vehicle
   Raise the rear of the vehicle at the manufacturer-specified lift points using rubber pucks to protect the battery pack pinch-weld seams. Support on jack stands rated for EV weight. Remove the rear wheel.
   ⚠Lifting at any point other than the designated pads can crush the HV battery enclosure.
2. 2

   Remove the brake caliper and bracket
   Unbolt the rear caliper bracket bolts and remove the caliper assembly (caliper + bracket together). Suspend it from the coil spring or subframe with wire — do NOT let it hang by the flexible brake hose. Remove the brake rotor (it may be retained by a small Phillips/Torx cover screw).
3. 3

   Disconnect the ABS/wheel speed sensor
   Remove the ABS sensor retaining bolt at the knuckle and carefully withdraw the sensor. Unclip the harness from any retainers on the trailing arm. Set the sensor aside protected — do not pull on the cable.
   ⚠ABS sensors are fragile; if seized in the bore, work it free with penetrant — do not pry on the sensor body.
4. 4

   Remove the axle nut
   With the previously broken-loose axle nut, fully remove it now. Discard — do not reuse. Push the half-shaft splined stub inward slightly to free it from the hub. If it is seized in the hub splines, use a soft mallet on the stub end (protect threads with a sacrificial nut) or a hub puller.
   ⚠Do not hammer directly on the axle threads. Thread an old nut on flush to protect them if persuasion is required.

5. 5

   Support and disengage the half-shaft
   Support the half-shaft with a bungee or stand. Pull the outer stub out of the hub splines. It is not necessary to remove the inner CV from the rear drive unit for hub replacement; simply allow the shaft to hang clear of the hub face. Do not let the inner CV joint over-articulate.
6. 6

   Remove the hub assembly mounting bolts
   Working from the inboard side of the knuckle, remove the rear hub assembly mounting bolts (accessed through the back of the knuckle). Note bolt orientation. Bolts may be threadlocked from the factory and require significant breakaway torque.

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

   Remove the old hub
   Pull the hub assembly off the front of the knuckle. If corroded in place, tap evenly around the perimeter with a soft-face mallet, or use a hub puller. Clean the knuckle bore and mounting face thoroughly with a wire brush — any rust or debris will cause uneven seating and runout.
   ⚠Do not strike the aluminum knuckle directly with a steel hammer.
8. 8

   Install the new hub assembly
   Test-fit the new hub to confirm the mounting face is fully seated against the knuckle with no gap. Apply medium-strength threadlocker to the hub bolts if specified by the OEM. Install bolts hand-tight first, then tighten in a cross pattern.

9. 9

   Re-engage the half-shaft
   Slide the half-shaft outer splines back through the new hub. Ensure splines align cleanly — do not force. Install the NEW axle nut hand-tight at this stage.
10. 10

    Reinstall ABS sensor, rotor, and caliper
    Clean the ABS sensor bore, reinstall the sensor and bolt. Install the rotor (with retaining screw if used). Reinstall the caliper/bracket assembly with threadlocker on the bracket bolts. Reconnect any harness clips.
11. 11

    Final axle nut torque (with wheel loaded)
    Reinstall the road wheel and snug the lug nuts. Lower the vehicle so the suspension is loaded (or have an assistant firmly apply the brake pedal). Torque the new axle nut to the verified specification, then stake/peen the collar into the half-shaft groove per OEM procedure.
    ⚠Failure to stake the new axle nut can allow it to back off in service — a critical safety issue.

Reassembly

1. Final-torque the wheel lug nuts in a star pattern with the wheel on the ground.
2. Reconnect the 12V low-voltage battery.
3. Exit Jack Mode via the touchscreen.
4. Cycle the brake pedal several times before driving to seat the caliper pistons.
5. Clear any ABS/stability faults that may have set during the repair using the touchscreen service menu (or allow them to self-clear after a short low-speed drive).

Verification

• Confirm no ABS, traction control, or stability warnings on the instrument cluster after a short test drive.
• Listen for bearing growl/howl that changes with cornering load — indicates improper seating or a defective new bearing.
• Re-check the axle nut staking and that the nut has not loosened after the first 50–100 miles.
• Recheck wheel lug torque after ~50 miles (Tesla recommends a re-torque after wheel service).
• Reminder: Tesla recommends rear drive unit gear oil service at ~12,500 mi initial then every 25,000–50,000 mi — if the vehicle is approaching that interval, plan it separately. Tire rotation every 6,250 mi is also recommended for Model Y Performance to limit rear tire wear.
