Solution

1. Preparation

Tools Required: Safety gloves, jack stands, wheel chocks, socket set, and torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off. Engage the parking brake.

2. Inspect and Replace Power Steering Fluid

Check the power steering reservoir for fluid level.
If low, fill it with the manufacturer-recommended fluid.
If the fluid is dark or contaminated, drain and replace it with fresh fluid.

3. Inspect CV Joints

Tools Required: Jack and jack stands, socket set.
Raise the front of the vehicle and secure it with jack stands.
Inspect the outer and inner CV joints for grease leakage or torn boots.
If damaged, remove the axle shaft and replace the CV joint or axle assembly.

4. Check Wheel Bearings

Spin the front wheels by hand while the vehicle is raised.
Listen for any grinding noise indicating a bad wheel bearing.
If noise is present, remove the wheel and brake assembly.
Replace the wheel bearing if necessary, ensuring proper torque specifications during reassembly.

5. Inspect Suspension Components

Visually inspect struts, control arms, and bushings for wear or damage.
If any components are worn, replace them according to the manufacturer’s specifications.
