Solution

1. Preparation

Tools Required: Jack, jack stands, torque wrench, tire pressure gauge, diagnostic scanner.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety if working on electrical components.

2. Tire Inspection and Replacement (if necessary)

Sub-steps:
1. Remove the wheel covers (if applicable).
2. Check tire pressure using a tire pressure gauge and inflate to the recommended PSI.
3. Inspect tires for uneven wear patterns or visible damage; replace if necessary.
4. Reinstall wheel covers and torque lug nuts to manufacturer's specifications (typically 80-100 ft-lbs).

3. Driveshaft and CV Joint Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Inspect the driveshaft for any signs of damage or misalignment.
3. Check CV joints for boot tears or grease leakage; replace if damaged.
4. Reassemble any components after inspection.

4. Suspension Component Inspection

Sub-steps:
1. Examine suspension components for physical damage or excessive play.
2. Tighten any loose bolts or replace worn-out bushings and struts.
3. Reassemble and lower the vehicle back to the ground.

5. Final Checks

Sub-steps:
1. Reconnect the battery if it was disconnected.
2. Use a diagnostic scanner to clear any error codes and verify no new codes appear after the repair.
