Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, OBD-II scanner, socket set, torque wrench.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Power Steering Fluid

Check the power steering fluid reservoir for low levels.
If fluid is low, top it off with the manufacturer's recommended fluid.
If fluid is dirty or contaminated, perform a complete fluid flush and replace.

3. Replace Worn Suspension Components

Tools Required: Socket set, torque wrench.
Lift the vehicle and remove the wheel.
Inspect control arms, bushings, and struts for wear or damage.
Replace any damaged components with OEM parts, ensuring to torque to manufacturer specifications.

4. Inspect and Replace Brake Components

Remove the wheel to access the brake assembly.
Inspect brake pads for wear and rotors for scoring or warping.
Replace worn pads and machined or replaced rotors as necessary, following proper installation procedures.

5. Inspect and Replace Wheel Bearings

With the vehicle lifted, spin the wheel to check for grinding noise.
If noise is present, remove the wheel and brake assembly to access the wheel bearing.
Replace the wheel bearing, ensuring proper alignment and torque specifications during installation.
