Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; if low, refill with the manufacturer-recommended fluid.
Start the engine and turn the steering wheel to circulate the fluid, then check the level again.

3. Inspect CV Joints

Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels using a socket set.
Inspect the outer CV joints for torn boots and grease leakage.
If damaged, replace the CV joint or axle as necessary.

4. Examine Wheel Bearings

With the vehicle still lifted, grasp the wheel at the top and bottom.
Shake the wheel; if there’s play, remove the brake caliper, rotor, and hub assembly.
Inspect the wheel bearing for wear; if it feels rough or has excessive play, replace it.

5. Assess Suspension Components

Visually inspect the struts, control arms, and bushings for any signs of wear or damage.
If any components are worn, replace them according to service manual specifications.

6. Reassemble and Test

Reinstall all components in the reverse order of removal.
Ensure all bolts are tightened to the manufacturer’s torque specifications.
Reconnect the battery and lower the vehicle.
Perform a test drive to check for the absence of grinding noise.
