Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is at normal operating temperature.

2. Inspect and Replace Worn Components

Tools Required: Socket set, wrench set, torque wrench, pry bar
Inspect and replace any worn suspension components:
- Control arms: Remove the bolts securing the control arms and replace them with new ones. Torque to specifications (usually around 60-80 Nm).
- Bushings: Use a pry bar to remove old bushings, and press new ones in place.
- Tie rods: Unbolt the tie rod ends from the steering knuckle, and replace them as necessary.

3. Perform Wheel Alignment

Tools Required: Wheel alignment machine
Align the wheels according to manufacturer specifications:
- Adjust the camber, caster, and toe angles using the alignment machine.
- Ensure each angle is set within the specified range provided in the service manual (typically:
  - Camber: -0.5° to -1.5°
  - Caster: +7.0° to +8.0°
  - Toe: 0° to +0.1°).
After adjustments, re-check all angles to confirm they are within specification.

4. Test Drive and Final Adjustments

Go for a test drive to ensure the vehicle drives straight and the steering wheel is centered.
If further adjustments are needed, return to the alignment machine and make necessary corrections.
