Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Steering Components

Inspect Tie Rods:
- Use a socket set to remove the tie rod ends from the steering knuckle.
- Check the tie rods for any signs of wear or damage.
- If worn, replace with new tie rods. Torque to manufacturer specifications (typically around 50 lb-ft).
Inspect Ball Joints:
- Check ball joints for play by lifting the vehicle and shaking the wheel.
- If worn, replace the ball joints as necessary. Properly torque to specifications (usually 45-55 lb-ft).

3. Check and Adjust Wheel Alignment

Perform Wheel Alignment:
- Take the vehicle to a professional alignment shop.
- Ensure the camber, caster, and toe are adjusted to manufacturer specifications.

4. Inspect and Replace Power Steering Fluid

Check Fluid Level:
- Locate the power steering reservoir and check the fluid level.
- If low, fill with the recommended power steering fluid (check owner’s manual for specifications).
Inspect for Leaks:
- Look for any signs of leaks in the power steering system; repair hoses or seals as necessary.
