Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts.
Gather necessary tools and parts.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir under the hood.
2. Remove the cap and check the fluid level; add fluid if low.
3. If the fluid is dark or contaminated, perform a complete fluid change.
4. To change the fluid, connect a fluid pump to the reservoir and drain the old fluid.
5. Refill with manufacturer-recommended power steering fluid.

3. Check and Replace Steering Components

Sub-steps:
1. Inspect the steering rack and pinion for any signs of wear or damage.
2. Examine the tie rods and ball joints for play or grinding.
3. If any components are damaged, remove them using a socket set.
4. Replace with OEM or quality aftermarket parts, ensuring proper torque specifications are followed (typically around 35-50 lb-ft for tie rod ends).
5. Reassemble and secure all components.

4. Tire Inspection and Replacement

Sub-steps:
1. Remove front tires to inspect for uneven wear.
2. Measure tread depth; replace tires if below manufacturer specifications.
3. If uneven wear is present, perform a wheel alignment.
4. Install tires back onto the vehicle, ensuring proper torque (typically around 100 lb-ft for lug nuts).
