Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Brake Components

Remove the wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect the brake pads and rotors:
- Examine the thickness of the brake pads; if they are below 3mm, replace them.
- Check the surface of the rotors for scoring or uneven wear.
Replace brake pads:
- Remove the caliper bolts using a socket wrench.
- Slide off the caliper and hang it using a bungee cord to avoid strain on the brake line.
- Remove the old brake pads and install new pads, ensuring they are properly seated.
Replace or resurface rotors (if needed):
- If rotors are damaged, remove them by unscrewing the retaining screws.
- Install new rotors or have existing ones resurfaced if within specification.

3. Check and Replace Wheel Bearings

Remove the wheel hub:
- Remove any brake components that obstruct access to the wheel bearing.
- Use a socket set to remove the hub assembly.
Inspect the wheel bearing:
- Spin the bearing to check for smoothness; any grinding indicates replacement is necessary.
Replace the wheel bearing:
- Use a bearing puller to remove the old bearing.
- Press in the new bearing using a suitable tool or bearing installation tool.
- Reassemble the hub, ensuring all components are torqued to manufacturer specifications.

4. Reassemble

Reinstall the wheel and lug nuts, tightening to the manufacturer’s torque specification.
Reconnect the battery and lower the vehicle.
