Solution

1. Tire Inspection

Sub-steps:
1. Visually inspect tires for uneven wear patterns or bulges.
2. Measure tire pressure using a tire gauge and inflate to the manufacturer’s specifications (found on the driver’s door jamb).
3. If wear is uneven, rotate tires and align wheels as needed.

2. Wheel Balancing

Sub-steps:
1. Remove the wheel from the hub using a socket set.
2. Take the wheel to a tire shop for balancing.
3. Reinstall the wheel using a torque wrench to tighten lug nuts to the manufacturer’s recommended torque specification (typically around 100-120 lb-ft).

3. Suspension Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect control arms, ball joints, and bushings for any signs of wear or damage.
3. Replace any worn components with OEM parts.
4. Reassemble and torque bolts to the specified settings.

4. Driveshaft and CV Joint Check

Sub-steps:
1. Inspect the driveshaft for any visible damage or play.
2. Check CV joints for grease leaks or tears in the rubber boot.
3. If damaged, replace the driveshaft or CV joint as necessary, following the manufacturer's specifications for installation and torque values.
