Solution

1. Tire Inspection

Sub-steps:
1. Measure tire pressure using a tire gauge and inflate to manufacturer specifications.
2. Look for cracks, bulges, or punctures on the tire surface.
3. Check tread depth using a tread depth gauge; replace tires if tread is below 2/32".

2. Wheel Balancing

Sub-steps:
1. Remove the wheel and tire assembly from the vehicle.
2. Take the wheel to a tire shop or use a tire balancing machine.
3. Add or reposition wheel weights to achieve proper balance.
4. Reinstall the wheel and torque lug nuts to the manufacturer's specification.

3. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect control arms, bushings, and sway bar links for wear or damage.
3. Replace any worn suspension parts with OEM or quality aftermarket components.

4. Wheel Alignment

Sub-steps:
1. Use a wheel alignment system to assess the alignment angles.
2. Adjust camber, caster, and toe angles to meet manufacturer specifications.
3. Test drive the vehicle to ensure the steering feels centered and stable.

5. Driveshaft Inspection

Sub-steps:
1. Inspect the driveshaft for signs of bending or damage.
2. Check for worn U-joints and replace if necessary.
3. Ensure all bolts are tight and secure.
