Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers if applicable.
2. Use a tire pressure gauge to check each tire's pressure; inflate to recommended PSI if low.
3. Inspect tread depth using a tread depth gauge; replace tires if tread is worn beyond safe limits.
4. If tires are damaged, replace with OEM or quality aftermarket tires.
Tools Required: Tire pressure gauge, tire changing tools.

3. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Visually inspect control arms, tie rods, and bushings for cracks or play.
3. Replace any worn or damaged suspension components with OEM parts.
Tools Required: Jack, jack stands, socket set.

4. Drivetrain Inspection

Sub-steps:
1. Inspect the driveshaft for any signs of bending or damage.
2. Check the U-joints for wear; replace if any play is detected.
3. Ensure the axles are properly aligned and free of excessive play; replace as necessary.
Tools Required: Socket set, torque wrench.

5. Reassemble and Test

Sub-steps:
1. Reassemble all components and ensure everything is torqued to manufacturer specifications.
2. Reinstall wheels and lower the vehicle.
3. Test drive to confirm the shaking has been resolved.
Tools Required: Torque wrench.
