Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Tools Required: Wheel alignment machine, tire pressure gauge, jack and jack stands, torque wrench.

2. Tire Inspection and Adjustment

Inspect Tires:
- Check all four tires for uneven wear and confirm proper inflation.
- Adjust tire pressures to manufacturer specifications.
Rotate Tires:
- If uneven wear is noted, rotate tires to promote even wear.

3. Wheel Alignment Adjustment

Set Up Alignment Machine:
- Attach alignment heads to each wheel according to the machine’s instructions.
- Ensure vehicle is at the correct ride height with no load.
Measure Alignment Angles:
- Record the current camber, caster, and toe angles.
Make Adjustments:
- Adjust camber by loosening the strut bolts and repositioning the strut.
- Adjust toe using the tie rod ends; loosen lock nuts and rotate as necessary.
Verify Adjustments:
- Recheck all angles after adjustments to ensure they meet manufacturer specifications.

4. Final Checks

Test Drive:
- Take the vehicle for a test drive to verify handling and steering response.
Re-check Tire Pressure:
- Ensure all tires are still at the correct pressure post-alignment.
