Solution

1. Tire Inspection and Maintenance

Sub-steps:
1. Remove the wheel covers if applicable.
2. Inspect each tire for visible damage (cuts, bulges).
3. Check tire pressure and adjust to the manufacturer’s specifications.
4. Rotate tires if uneven wear is identified.
5. Replace damaged tires if necessary.

2. Wheel Balancing and Alignment

Tools Required: Wheel balancing machine, alignment tools.
Sub-steps:
1. Mount each wheel on the balancing machine to check for imbalances.
2. Add weights as necessary to balance each wheel.
3. Perform a four-wheel alignment to ensure proper angles and reduce vibrations.

3. Suspension Component Inspection

Tools Required: Jack, jack stands, wrench set.
Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Visually inspect all suspension components for signs of wear or damage.
3. Replace any worn or damaged components (shocks, struts, control arms).

4. Drivetrain Inspection

Tools Required: Torque wrench, socket set.
Sub-steps:
1. Inspect the driveshaft for any cracks or play in the joints.
2. Tighten any loose bolts on the driveshaft to the manufacturer’s torque specifications.
3. Replace any damaged CV joints or driveshaft components.
