Problem Statement

Learn how to diagnose and fix wheel bearing noise in Tesla Model S Plaid. Step-by-step guide with symptoms, diagnostic steps, and repair instructions.

Affected Component

Suspension

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is on a flat surface and securely supported by jack stands before working underneath.

Symptoms

•Unusual humming or grinding noise while driving, especially at higher speeds
•Noise increases or decreases with vehicle speed, not dependent on engine RPM
•Vibration felt through the steering wheel or chassis
•Clicking or popping sound when turning
•Uneven tire wear observed on affected wheels

Diagnostic Steps

1
Check for any visible damage or debris on the wheel and brake components.
2
Elevate the vehicle using a jack and manually spin each wheel to listen for any abnormal noises.
3
Drive the vehicle at various speeds while listening for any consistent humming or grinding sounds.
4
During the road test, take turns while cornering to see if the noise changes, indicating bearing wear.
5
Ensure all tires are properly inflated as incorrect pressure can sometimes mimic bearing noise.
6
Compare the sound from the suspect wheel to the opposite side to identify differences in noise levels.

Solution

Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Torque wrench
- Socket set
- Screwdriver set
- Stethoscope or mechanic's listening device
Safety Warnings:
- Always ensure the vehicle is on a flat surface and securely supported by jack stands before working underneath.

2. Remove Wheel

Loosen the lug nuts on the wheel suspected of having a bad bearing.
Lift the vehicle using the jack and securely place it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Wheel Bearing

Visual Inspection: Look for any signs of damage, rust, or excessive play in the wheel hub.
Check for Play: Grip the wheel at the 12 and 6 o'clock positions and rock it back and forth to check for excessive movement.
Listen for Noise: Use a stethoscope or mechanic's listening device to listen to the wheel bearing while rotating the wheel. Any grinding or roughness indicates a worn bearing.

4. Replace Wheel Bearing (if necessary)

Remove Brake Components: If bearing replacement is necessary, remove the brake caliper and rotor to access the wheel bearing.
Remove Hub Assembly: Use the appropriate socket to remove the hub assembly bolts. Carefully pull the hub assembly off to reveal the bearing.
Install New Bearing: Press in the new wheel bearing using a bearing press tool, ensuring it is seated properly.
Reassemble the hub assembly, brake rotor, and caliper, ensuring all bolts are torqued to the manufacturer's specifications.

5. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and then torque the lug nuts to the specified torque setting.
