Solution

1. Preparation

Gather tools and parts required for the repair.
Safety check: Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Worn Components

Inspect Steering Components:
- Remove the front wheels using a socket set.
- Check tie rods and ball joints for play by gripping and moving them; replace if any play is detected.
Replace Components (if needed):
- Tie Rod Ends:
  - Use a wrench to remove the tie rod end from the steering knuckle.
  - Install the new tie rod end and torque it to the manufacturer's specification (typically around 50-70 ft-lbs).
- Ball Joints:
  - Remove the control arm if the ball joint is integrated; follow service manual specifications for removal.
  - Install the new ball joint and torque to specifications (usually around 30-50 ft-lbs).

3. Wheel Alignment

After replacing any worn components, perform a wheel alignment using a professional alignment machine.
Adjust camber, caster, and toe settings to meet manufacturer specifications.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Test drive the vehicle to check for improvements in steering feel and response.
