Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, basic socket set.
Safely park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, top off with the recommended fluid type.
If the fluid appears dirty or contaminated, drain and replace it.

3. Check and Replace CV Joints

Lift 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 tears or leaks; replace if necessary.
If the CV joints are damaged, remove the axle nut, disconnect the joint from the hub, and replace with a new CV joint.

4. Inspect Wheel Bearings

Spin the wheel by hand to check for roughness or noise.
If the bearing is faulty, remove the wheel and brake caliper, and then remove the hub assembly.
Replace the bearing with a new one, ensuring proper grease and assembly.

5. Examine Suspension Components

Visually inspect struts, control arms, and bushings for any signs of wear or damage.
Replace any damaged components, ensuring all bolts are torqued to manufacturer specifications.
