Solution

1. Preparation

Gather tools and equipment: jack, jack stands, tire pressure gauge, lug wrench, wheel balancer, alignment machine.
Ensure the vehicle is on a flat, stable surface.

2. Tire Inspection

Sub-steps:
1. Use a tire pressure gauge to check each tire's pressure.
2. Inflate or deflate tires to the recommended pressure (typically found on a sticker inside the driver's door).
3. Visually inspect tires for any visible damage or uneven wear patterns.
4. Replace any damaged tires as necessary.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel and tire assembly using a lug wrench.
2. Mount the wheel on a wheel balancer.
3. Follow the balancer's instructions to determine the required balancing weights.
4. Attach the weights to the rim as specified.
5. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs).

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop or use an alignment machine.
2. Adjust the toe, camber, and caster settings to the factory specifications.
3. Test drive post-alignment to confirm improvement.

5. Suspension and Mount Inspection

Sub-steps:
1. Visually inspect suspension components for any signs of wear or damage, such as leaking shocks or worn bushings.
2. Replace any worn or damaged components as necessary.
3. Check engine and transmission mounts for degradation and replace if necessary.
