Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the battery if working on electronic components.

2. Tire Inspection and Replacement

Inspect Tires:
- Remove the wheel covers (if applicable).
- Visually inspect each tire for irregular wear, bulges, or punctures.
- Use a tire depth gauge to measure tread depth.
Replace Tires (if necessary):
- Use a lug wrench to loosen lug nuts while the vehicle is on the ground.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the lug nuts and take off the tire.
- Install the new tire, hand-tighten lug nuts, then lower the vehicle.
- Torque the lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).

3. Wheel Balancing

Balance Tires:
- Remove the wheel and tire assembly.
- Mount the tire on a wheel balancer.
- Follow the balancer's instructions to add weights as necessary to achieve balance.
- Reinstall the wheel and torque the lug nuts.

4. Wheel Alignment

Align Wheels:
- Use an alignment tool to check the alignment angles.
- Adjust camber, caster, and toe as necessary using the adjustment bolts.
- Test drive the vehicle to ensure straight tracking.

5. Suspension Inspection and Repair

Inspect Suspension:
- Check for worn bushings, ball joints, and shocks/struts.
- Replace any worn components as needed.
- Tighten all suspension components to manufacturer specifications.

6. Driveline Inspection

Inspect Driveline Components:
- Examine U-joints and CV joints for play or wear.
- Replace any components that show signs of damage.
