Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, brake cleaner, and flashlight.
Safety Warnings: Ensure the vehicle is on a level surface and the parking brake is engaged. Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Pads (if necessary)

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect the brake pads for wear; replace if the thickness is below 3mm.
4. Remove the caliper bolts and slide the caliper off the rotor.
5. Replace the old pads with new ones and apply brake grease to the backing of the pads to reduce noise.
6. Reattach the caliper and torque bolts to the manufacturer's specifications (usually around 25-35 ft-lbs).
7. Reinstall the wheel and lower the vehicle.

3. Inspect and Replace Wheel Bearings (if necessary)

Sub-steps:
1. With the wheel still removed, check for bearing play by rocking the hub.
2. If play is detected, remove the brake rotor and caliper as previously described.
3. Remove the wheel hub assembly by unbolting it from the steering knuckle.
4. Replace with a new wheel bearing assembly and torque bolts to manufacturer specifications (usually around 40-50 ft-lbs).
5. Reassemble the brake components and wheel.
