Solution

1. Tire Inspection

Sub-steps:
- Measure tire pressure using a tire gauge; adjust to recommended PSI.
- Inspect tread depth and look for signs of uneven wear; replace tires if necessary.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Mount the wheels on a wheel balancer; adjust weights until balanced.
- Reinstall wheels and torque lug nuts to manufacturer specifications (typically 76-86 ft-lbs).

3. Suspension Inspection

Sub-steps:
- Raise the vehicle securely on jack stands.
- Visually inspect control arms, bushings, and struts for wear or damage.
- Replace any damaged suspension components with OEM or quality aftermarket parts.

4. Wheel Alignment

Sub-steps:
- After ensuring suspension is in good condition, take the vehicle to an alignment shop.
- Adjust toe, camber, and caster angles to manufacturer specifications (consult service manual for specific values).

5. Drivetrain Check

Sub-steps:
- Inspect the driveshaft for any visible damage or wear.
- Check CV joints for signs of grease leakage or wear; replace as necessary.
- Ensure all drivetrain components are securely fastened.
