Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat, level surface.
Engage the parking brake and wear safety goggles.

2. Tire Inspection and Replacement (if necessary)

Remove the Tires
- Use a lug wrench to loosen lug nuts.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts completely and take off the tires.
Inspect Tires
- Check for bulges, cuts, or punctures.
- Measure tread depth using a tread depth gauge; replace if below 2/32".
Reinstall Tires
- If tires are in good condition, reinstall them and torque the lug nuts to manufacturer specifications (usually 100-120 ft-lbs).

3. Wheel Balancing

Mount Tires on Balancer
- Place the removed tires on a wheel balancer.
Balance Adjustment
- Follow the machine's instructions to add weights where needed.
- Ensure that each tire is balanced properly before reinstalling.

4. Wheel Alignment

Set Alignment Machine
- Attach the alignment equipment to each wheel.
Adjust Alignment
- Adjust the camber, caster, and toe angles to match manufacturer specifications.

5. Suspension Inspection

Visual Inspection
- Check all suspension components for signs of wear or damage.
Replace Worn Components
- If any components are worn or damaged, replace them accordingly, ensuring proper torque specifications are followed during reinstallation.
