Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect Power Steering System

Tools Required: OBD-II scanner, fluid syringe.
Check the power steering fluid level using the dipstick or cap.
- If low, top up with the manufacturer-recommended power steering fluid.
- If the fluid is dark or contaminated, consider flushing the system.

3. Inspect Suspension Components

Tools Required: Jack, jack stands, socket set.
Lift the vehicle and secure it on jack stands.
Inspect the control arms, bushings, and struts for wear or damage.
- Look for any cracks or excessive play in the components.
- Tighten any loose bolts to manufacturer specifications.

4. Examine Brake Components

Tools Required: Brake caliper tool, torque wrench.
Remove the wheel to access the brake components.
Inspect brake pads for uneven wear and check the condition of the rotors.
- Replace worn brake pads or rotors as necessary.
- Ensure caliper bolts are tightened to specifications.

5. Check CV Joints and Boots

Tools Required: Pliers, socket set.
Inspect the CV joints for any signs of grease leakage or damage to the boots.
- If the boot is damaged, replace it and re-grease the joint.
- Ensure the joint moves freely without grinding.
