Solution

1. Preparation

Tools Required: Tire pressure gauge, alignment machine, jack and jack stands, wheel balancer, socket set.
Ensure the vehicle is parked on a flat surface.
Disconnect the battery if working on electronic components.

2. Tire Inspection and Maintenance

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure of all tires.
- Inflate or deflate tires to the manufacturer’s recommended pressure.
Examine Tire Condition:
- Inspect for signs of uneven wear, bulges, or cracks.
- Replace any damaged tires.

3. Wheel Alignment

Set Up Alignment Machine:
- Drive the vehicle onto the alignment rack.
- Attach the alignment sensors to the wheels.
Perform Alignment:
- Follow the machine's prompts to adjust camber, caster, and toe according to the manufacturer's specifications.
- Tighten all adjustment points to the specified torque values.

4. Suspension Component Inspection

Visual Inspection:
- Raise the vehicle with a jack and secure with jack stands.
- Check for any signs of wear or damage on shocks, struts, and bushings.
Replace Worn Components:
- If any parts are worn, remove and replace them, ensuring to torque bolts to manufacturer specifications.

5. Wheel Balancing

Remove Wheels:
- Use a socket set to remove the wheel lug nuts and take off the wheels.
Balance Wheels:
- Mount each wheel on the wheel balancer and follow the machine’s instructions to add weights as needed.
Reinstall Wheels:
- Torque the lug nuts to the specified value in a crisscross pattern.
