Solution

1. Preparation

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

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels using a lug wrench.

3. Inspect and Replace Brake Components

Inspect Rear Brake Pads and Rotors:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor.
- Check the brake pads for thickness; replace them if they are worn down to 3mm or less.
- Inspect the rotor for scoring or excessive wear; replace it if necessary.
Replace Brake Pads:
- If needed, remove the old pads and install new ones, ensuring they are properly seated.
- Reinstall the caliper and torque the bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).

4. Check and Replace Wheel Bearings (if necessary)

Inspect Wheel Bearings:
- Spin the wheel hub to check for noise or roughness.
- If worn, remove the hub assembly and replace the wheel bearings.
Reassemble:
- Reinstall the wheel hub and torque the axle nut to the manufacturer's specification (usually around 150 ft-lbs).

5. Inspect and Repair Suspension Components (if necessary)

Check Suspension:
- Examine shock absorbers, struts, and control arms for any signs of wear or damage.
- Replace any worn components as needed.

6. Reassemble and Lower the Vehicle

Reinstall the rear wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specification (typically around 76 ft-lbs).
