Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts with a lug wrench slightly while the vehicle is on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Fully remove the lug nuts and take off the wheel.

3. Remove Brake Components

Sub-steps:
1. Remove the caliper by unscrewing the caliper bolts using a socket set (typically 13mm or 15mm).
2. Secure the caliper with a wire or bungee cord to avoid straining the brake line.
3. Remove the brake rotor by unscrewing any retaining screws if applicable.

4. Inspect and Replace Wheel Bearing

Sub-steps:
1. Remove the hub assembly by unscrewing the retaining bolts (use a torque wrench to ensure proper tightening upon reinstallation).
2. Carefully extract the old wheel bearing using a bearing puller.
3. Clean the hub assembly area and apply new grease.
4. Install the new wheel bearing into the hub, ensuring it is seated correctly.

5. Reassemble Components

Sub-steps:
1. Reattach the hub assembly and tighten the retaining bolts to the manufacturer's specifications.
2. Reinstall the brake rotor and secure it with any retaining screws.
3. Reattach the brake caliper and tighten the caliper bolts.
4. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Sub-steps:
1. Lower the vehicle from the jack stands using the jack.
2. Tighten the lug nuts to the specified torque settings (typically 100-120 Nm).
3. Perform a final inspection of all components.
