Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, flashlight.
Sub-steps:
1. Park the vehicle on a level surface and set the parking brake.
2. Gather all necessary tools and safety equipment (gloves, safety glasses).
3. Disconnect the negative battery terminal to ensure safety while working on the braking system.

2. Inspect and Replace Rear Brake Pads

Sub-steps:
1. Loosen the lug nuts on the rear wheels while the vehicle is on the ground.
2. Lift the rear of the vehicle using a jack and secure it with jack stands.
3. Remove the rear wheels using the lug wrench.
4. Remove the caliper by loosening the caliper bolts and carefully lifting it off the rotor. Support the caliper with a bungee cord to avoid stress on the brake line.
5. Inspect the brake pads for thickness. Replace if they are below 3mm or have uneven wear.
6. Clean the rotor surface with brake cleaner to remove any debris or dust.
7. If the rotor is scored or damaged, replace it accordingly.

3. Check and Replace Wheel Bearings

Sub-steps:
1. With the wheel still removed, grab the rear hub and check for any play by rocking it back and forth.
2. If there is noticeable play, remove the hub assembly according to service manual specifications.
3. Inspect the wheel bearings for wear or damage. If necessary, replace with new bearings.
4. Reassemble the hub and torque the bolts to the manufacturer’s specifications.

4. Inspect Suspension Components

Sub-steps:
1. Visually check all suspension components for signs of wear or damage (bushings, control arms, struts).
2. Replace any worn or damaged components as necessary, following the specific torque specifications for each part.

5. Reassemble and Test

Sub-steps:
1. Reinstall the caliper and tighten the caliper bolts to the specified torque.
2. Reinstall the rear wheels and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
4. Reconnect the negative battery terminal.
5. Test drive the vehicle to ensure the grinding noise has been resolved.
