Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Wheel Bearings

Remove the Wheel:
- Use a socket set to loosen and remove the lug nuts.
- Take off the wheel and set it aside.
Inspect the Wheel Bearing:
- Spin the hub to check for roughness or grinding.
- Use a multimeter to check for continuity if applicable.
Remove the Old Wheel Bearing:
- Remove the brake caliper and bracket (use a torque wrench for reinstallation).
- Detach the axle nut using an impact wrench if necessary.
- Use a bearing puller to remove the old wheel bearing from the hub.
Install the New Wheel Bearing:
- Clean the hub area thoroughly.
- Press the new wheel bearing into the hub using a bearing press.
- Reinstall the axle nut and torque it to the manufacturer's specifications.

3. Reassemble Components

Reinstall the Brake Caliper:
- Position the caliper over the rotor and secure it with the bracket bolts.
- Torque the caliper bolts to the specified value.
Reattach the Wheel:
- Place the wheel onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the specified value.
Reconnect the Battery:
- Reconnect the negative battery terminal.
