Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Tools Required: Jack and jack stands, torque wrench, socket set, screwdriver set, brake cleaner, stethoscope (or similar listening device).

2. Raise the Vehicle

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

3. Inspect Brake Components

Remove the brake caliper and rotor.
- Sub-steps:
  - Loosen caliper bolts and safely hang the caliper to avoid stress on the brake line.
  - Remove the rotor, checking for any scoring or damage.
Inspect brake pads for uneven wear or debris.
Replace any damaged components with OEM parts if necessary.

4. Examine Suspension and Wheel Bearings

Inspect the rear suspension components (shocks, struts, springs).
- Sub-steps:
  - Check for leaks, cracks, or broken parts.
Check wheel bearings for play or noise.
- Sub-steps:
  - Spin the wheel while listening for grinding noises.
  - If damaged, replace bearings following manufacturer specifications.

5. Check Differential Fluid

If the noise persists, inspect the rear differential fluid.
- Sub-steps:
  - Remove the fill plug and check fluid level and condition (should be clean and free of metal shavings).
  - If necessary, drain and replace with the correct type of fluid.

6. Reassemble and Lower Vehicle

Reinstall the brake rotor and caliper.
Reattach the wheels, ensuring the lug nuts are torqued to the manufacturer's specifications.
Lower the vehicle and remove jack stands.
