Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, torque wrench, tire pressure gauge, wheel alignment tool.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection and Replacement

Sub-steps:
- Check tire pressure using the tire pressure gauge; inflate to the recommended PSI if needed.
- Inspect tires for uneven wear, bulges, or damage.
- If tires are damaged or excessively worn, replace them with new tires.

3. Wheel Alignment

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Use a wheel alignment tool to measure the alignment angles.
- Adjust the camber, caster, and toe settings to match the manufacturer’s specifications.

4. Driveshaft and Axle Inspection

Sub-steps:
- Inspect the driveshaft and axles for visible damage such as bends or cracks.
- Check the CV joints for wear or grease leaks.
- If any components are damaged, replace them with OEM or high-quality aftermarket parts.

5. Reassemble and Test

Sub-steps:
- Reinstall any components that were removed during inspection.
- Lower the vehicle and torque the wheel lug nuts to the manufacturer’s specifications.
- Test drive the vehicle to ensure the shaking has been resolved.
