Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect and Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Lift the front of the vehicle using the jack and secure it with jack stands.
Remove the left front wheel using the lug wrench.

3. Inspect Brake Components

Visually inspect the brake pads and rotors for signs of wear or damage.
If pads are worn down to the indicator, replace them.
Check the rotors for any scoring or warping. Replace if necessary.
Parts Required: Brake pads (if worn), rotors (if damaged).

4. Check CV Joint

Inspect the CV joint boot for tears or leaks.
If the boot is damaged, replace the CV joint assembly.
Tools Required: Socket set, CV joint puller (if necessary).
Parts Required: CV joint assembly (if damaged).

5. Power Steering Inspection

Check the power steering fluid level. If low, top it off with the recommended fluid type.
Inspect for leaks in the power steering hoses and the pump.
Replace any damaged components as needed.
Parts Required: Power steering fluid, hoses (if damaged).

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and finish tightening the lug nuts to the manufacturer's torque specifications (typically around 76 ft-lbs for RAV4).
Reconnect the negative battery terminal.
