Solution

1. Preparation

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

2. Inspect Steering Components

Sub-steps:
- Raise the front of the vehicle using a jack and secure it with jack stands.
- Remove the front wheels to gain access to the steering and suspension components.
- Check the tie rods for any signs of wear or looseness by manipulating them side to side.
- Inspect the ball joints for any play or damage by attempting to move the wheel in a vertical motion.

3. Replace Worn Components

Sub-steps:
- If any components are found to be worn, such as tie rods or ball joints, replace them with new parts.
- Use a socket set to remove the worn components and install new ones, ensuring that all fasteners are torqued to manufacturer specifications (consult the service manual for specific torque values).
- Reinstall the front wheels and lower the vehicle back to the ground.

4. Check and Replenish Power Steering Fluid

Sub-steps:
- Locate the power steering reservoir and check the fluid level.
- If low, add the manufacturer-recommended power steering fluid until it reaches the proper level.
- Start the engine and turn the steering wheel from lock to lock to bleed any air from the system.

5. Alignment Check

Sub-steps:
- After replacing components, perform a wheel alignment to ensure proper handling and tire wear.
- Adjust the alignment settings to the manufacturer specifications.
