Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench, brake cleaner, jack and jack stands.
Remove the wheel where the noise is originating.
Inspect the brake pads and rotors for wear. If they are worn down:
- Remove the caliper bolts and take off the brake caliper.
- Replace the brake pads and clean the rotor surface with brake cleaner.
- Reattach the caliper and torque bolts to manufacturer specifications (typically around 70 ft-lbs).

3. Inspect and Replace CV Joint or Axles

Tools Required: Socket set, penetrating oil, torque wrench.
If CV joints are damaged:
- Raise the vehicle and secure it with jack stands.
- Remove the wheel and inspect the CV boot for tears.
- If the joint is worn, remove the axle nut with a breaker bar.
- Pull out the axle shaft from the hub assembly and replace with a new part.
- Reassemble and torque the axle nut to manufacturer specifications (usually around 150 ft-lbs).

4. Transmission Fluid Check

Tools Required: Funnel, transmission fluid.
Check the transmission fluid level using the dipstick (if applicable). If low:
- Add the appropriate fluid type specified in the owner’s manual.
- Ensure no leaks are present in the transmission system.
