Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Visually inspect all tires for uneven wear, bulges, or punctures.
2. Replace any damaged tires with new, manufacturer-approved tires.

2. Tire Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Mount the wheels on a wheel balancing machine.
3. Add weights to the rim until the wheel is balanced according to specifications.
4. Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically around 76 lb-ft).

3. Wheel Alignment

Sub-steps:
1. Use an alignment machine to measure the current alignment settings.
2. Adjust the camber, caster, and toe angles to meet manufacturer specifications.
3. Test drive after adjustments to ensure improved handling and reduced vibrations.

4. Suspension Component Inspection and Repair

Sub-steps:
1. Check all suspension components (struts, shocks, bushings) for signs of wear or damage.
2. Replace any worn or damaged parts with OEM or high-quality aftermarket components.
3. Reassemble suspension components and verify secure installation.
