Solution

1. Preparation

Gather necessary tools and equipment.
Ensure vehicle is on a flat, level surface.
Safety warning: Ensure the vehicle is securely lifted if working underneath.

2. Inspect and Adjust Tire Pressure

Check and adjust tire pressure for all four tires to manufacturer specifications.
Tools required: Tire pressure gauge, air compressor.

3. Perform Visual Inspection of Suspension Components

Inspect tie rods, control arms, and bushings for wear or damage.
Replace any worn components as needed.

4. Conduct Wheel Alignment

Position the vehicle on an alignment rack.
Adjust the camber, caster, and toe angles to meet manufacturer specifications.
- Camber should typically be between -0.5° and +0.5°.
- Caster should be around +5.5° to +7.5°.
- Toe should be set to 0° or slightly toe-in (0 to +0.1°).
Tools required: Wheel alignment machine, torque wrench.

5. Test Drive and Final Adjustments

After adjustments, conduct a test drive to ensure the vehicle tracks straight and handles properly.
Re-check alignment settings if necessary.
