Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Turn off the engine and engage the parking brake.

2. Gather Tools

Tools Required:
- Alignment tool (or laser alignment system)
- Tape measure
- Spirit level
- Wrenches or sockets for adjusting suspension components
- Jack and jack stands

3. Measure and Adjust Front Alignment

Sub-steps:
1. Use the alignment tool to check the camber angle on each front wheel. Adjust if necessary by loosening the bolts on the upper control arm and repositioning as needed.
2. Measure toe-in by measuring the distance between the front and rear edges of the front tires.
3. Adjust the tie rods to achieve the correct toe specification (typically between 0.05° to 0.15° toe-in).
4. Tighten all bolts to the manufacturer’s torque specifications.

4. Measure and Adjust Rear Alignment

Sub-steps:
1. Check the rear wheel camber using the alignment tool; adjust if necessary by modifying the rear control arm settings.
2. Measure the distance between the front and rear of the rear tires to check for toe. Adjust the toe by using the adjusting bolts on the rear suspension.
3. Ensure that all adjustments are within the manufacturer's specifications.
4. Recheck all angles once adjustments are made.
