3. Examine Steering Linkage

Sub-steps:
- Lift the front of the vehicle using a jack and secure it with jack stands.
- Visually inspect the tie rod ends, pitman arm, and idler arm for wear or damage.
- Wiggle the steering wheel back and forth to check for excessive play in the linkage.

4. Test Steering Gear

Sub-steps:
- Turn the steering wheel slowly from side to side while listening for abnormal noises.
- If noises are present, consider replacing the steering gear assembly.

5. Check Tire Condition

Sub-steps:
- Inspect all four tires for signs of uneven wear or damage.
- Measure tire pressure and adjust it to the recommended levels.
- If uneven wear is found, consider performing a wheel alignment.

6. Inspect Suspension Components
