Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Tools Required: Floor jack, jack stands, tire pressure gauge, torque wrench, wheel balancing machine.

2. Tire Inspection

Sub-steps:
1. Remove hubcaps or wheel covers if necessary.
2. Inspect each tire for visible damage and tread wear patterns.
3. Measure tire pressure with a gauge and inflate to the recommended PSI if needed.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel from the vehicle using a floor jack and secure it with jack stands.
2. Mount the wheel on a wheel balancing machine.
3. Check for imbalances and add wheel weights as necessary to achieve balance.
4. Reinstall the wheel onto the vehicle and torque the lug nuts to the manufacturer's specifications.

4. Suspension and Steering Component Inspection

Sub-steps:
1. Visually inspect all suspension components (shocks, struts, springs, etc.) and steering components for any signs of wear or damage.
2. If any components are worn or damaged, replace them according to manufacturer specifications.
3. Perform an alignment check if suspension components were replaced.
