Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Engage the parking brake and wear safety glasses.
Gather necessary tools and parts.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the rear or front wheels (depending on where the noise originates) using a socket set.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide off the caliper and hang it using a bungee cord (do not let it dangle by the brake line).
- Remove the old brake pads and inspect the caliper for damage.
- Install new brake pads, ensuring proper orientation and alignment.
Brake Rotors:
- If warped or damaged, remove the rotor by unscrewing the retaining bolts.
- Clean the hub surface and install the new rotor, ensuring it sits flush.

4. Check and Replace Wheel Bearings

Remove the hub assembly if the bearings are worn.
Use a bearing puller to extract the old bearing.
Install the new bearing using a press, ensuring it is seated properly.

5. Reassemble and Lower the Vehicle

Reinstall the caliper and tighten bolts to manufacturer specifications (usually 25-30 ft-lbs).
Reattach the wheel and lower the vehicle.
Tighten the lug nuts in a crisscross pattern to the recommended torque (typically 76 ft-lbs).
