Solution

1. Preparation

Tools Required: Jack and jack stands, torque wrench, tire pressure gauge, wheel balancer, alignment machine.
Ensure the vehicle is on a level surface and the engine is turned off.

2. Tire Inspection

Sub-steps:
1. Check tire pressure using the tire pressure gauge and adjust to manufacturer specifications.
2. Inspect each tire for uneven wear patterns; replace if necessary.
3. Check for any bulges or damage on the sidewalls.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using the jack and jack stands.
2. Mount each wheel on the wheel balancer.
3. Adjust weights as needed to ensure proper balance; repeat for all wheels.
4. Reinstall the wheels on the vehicle, ensuring proper torque specifications (typically around 100-120 Nm).

4. Wheel Alignment

Sub-steps:
1. Place the vehicle on the alignment machine.
2. Adjust the alignment according to manufacturer specifications for camber, caster, and toe.
3. Perform a test drive to verify that the vehicle tracks straight.

5. Suspension Inspection

Sub-steps:
1. Visually inspect suspension components for any signs of wear or damage.
2. Check for play in control arms and ball joints by applying pressure and observing for movement.
3. Replace any worn or damaged components as necessary.
