Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack, jack stands, alignment tool.
Ensure the vehicle is parked on a level surface.
Disconnect the battery if working on electrical components.

2. Inspect and Tighten Steering Components

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels for easier access to the steering components.
3. Inspect the steering linkage (tie rods, drag link) for looseness; tighten any loose connections to manufacturer specifications.
4. Torque the tie rod ends to the manufacturer-recommended values (typically around 30-50 ft-lbs, check specifications).

3. Check Power Steering System

Sub-steps:
1. Locate the power steering fluid reservoir and check the fluid level.
2. If low, add the appropriate type of power steering fluid (typically ATF or specific PS fluid).
3. Inspect hoses for leaks or wear; replace any damaged hoses.

4. Wheel Alignment

Sub-steps:
1. After tightening components, perform a wheel alignment.
2. Use an alignment tool to measure front and rear wheel angles.
3. Adjust caster, camber, and toe angles as necessary to meet manufacturer specifications.
