Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and block the rear wheels.
Disconnect the battery to ensure safety during the process.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts using a socket set while the wheel is still on the ground.
2. Lift the vehicle with a jack and secure it on jack stands.
3. Remove the wheel completely.

3. Remove Brake Components

Sub-steps:
1. Remove the brake caliper by unscrewing the caliper bolts.
2. Hang the caliper using a bungee cord to avoid straining the brake line.
3. Remove the brake rotor by unscrewing any retaining screws if present.

4. Inspect and Replace Wheel Bearing

Sub-steps:
1. Remove the hub assembly by loosening the axle nut and any bolts securing the hub.
2. Pull the hub assembly off the axle and inspect the wheel bearing for damage or excessive play.
3. If damaged, replace the wheel bearing with a new one, ensuring proper alignment and fit.
4. Reassemble by reversing the steps, ensuring all bolts are torqued to manufacturer specifications.

5. Reassemble Components

Sub-steps:
1. Reinstall the brake rotor and caliper, ensuring bolts are tightened to specifications.
2. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Check

Sub-steps:
1. Lower the vehicle off the jack stands.
2. Torque the lug nuts in a star pattern to the manufacturer's specified torque.
3. Reconnect the battery.
