Solution

1. Preparation

Gather tools: socket set, torque wrench, jack, jack stands, and safety goggles.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
- Locate the power steering reservoir and check fluid level.
- If low, top off with manufacturer-recommended power steering fluid.
- If fluid is dirty or contaminated, drain and replace the fluid completely.
Safety Warning: Ensure the engine is off and cool before working on the power steering system.

3. Check and Replace Wheel Bearings

Sub-steps:
- Raise the front of the vehicle using a jack and secure with jack stands.
- Remove the front wheel by loosening lug nuts with a socket wrench.
- Inspect the wheel bearing for any play by spinning the hub; it should rotate smoothly without grinding.
- If damaged, replace the wheel bearing by removing the hub assembly and pressing out the old bearing.
- Install the new bearing, reassemble the hub, and torque the lug nuts to the manufacturer’s specification.

4. Inspect and Replace Suspension Components

Sub-steps:
- Visually inspect control arms, tie rods, and bushings for signs of wear or damage.
- If any components are worn, replace them using a socket set. Ensure proper torque specifications are followed for reinstallation.
- Lubricate any grease fittings as needed.
