Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir and remove the cap.
Check the fluid level and top it up with the manufacturer-recommended fluid if low.
If the fluid is dirty or smells burnt, drain and replace it with new power steering fluid.

3. Inspect CV Joints and Boots

Raise the vehicle using a jack and secure it with jack stands.
Remove the front wheels to access the CV joints.
Inspect the CV boots for cracks or leaks; replace if damaged.
Check the CV joints for play or grinding; replace if necessary.

4. Check and Replace Wheel Bearings

Spin the wheel by hand to listen for grinding noises.
If noise is present, remove the wheel and brake assembly.
Remove the hub assembly and inspect the wheel bearing; replace if it feels rough or has play.
Reassemble in the reverse order, ensuring proper torque specifications are followed.

5. Inspect Brake Components

Check the brake calipers and pads for proper alignment and wear.
Ensure there is no contact between the brake components and steering/suspension parts.
Replace any worn brake pads or faulty calipers.

6. Suspension Components Inspection

Check for damaged or worn suspension parts like struts, control arms, and bushings.
Replace any damaged components to restore proper alignment and handling.
