Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery (if applicable).
Tools Required: Jack, jack stands, socket set, torque wrench, wheel bearing puller, hammer, and a mechanic's stethoscope.

2. Remove Wheel

Loosen the lug nuts using a socket wrench (do not fully remove yet).
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Brake Components

Remove the brake caliper by unbolting it and securing it away from the work area (do not hang it by the brake line).
Remove the brake rotor by taking off any retaining screws or clips if present.

4. Remove Wheel Bearing

Inspect the hub assembly to locate the wheel bearing.
Depending on the design, you may need to remove the hub nut using a socket wrench.
Use a wheel bearing puller to extract the old bearing from the hub. Ensure you do not damage the hub during this process.
Clean the hub area of any debris or old grease.

5. Install New Wheel Bearing

Apply a light coat of grease to the new wheel bearing and the hub assembly.
Press the new wheel bearing into place using the wheel bearing puller or a suitable tool.
Reinstall the hub nut and torque it to the manufacturer's specifications (typically around 150-200 Nm, but consult specific service manual for accuracy).

6. Reassemble Brake Components and Wheel

Reinstall the brake rotor and caliper, securing with bolts and ensuring proper torque.
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
