Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the negative battery terminal if any electrical components will be inspected.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Inspect tires for signs of uneven wear; replace if necessary.
3. Check tire pressure; inflate to the manufacturer-recommended psi.
4. Reinstall the wheel and torque lug nuts to the manufacturer's specifications.

3. Suspension Component Inspection

Sub-steps:
1. Visually inspect struts and shocks for leaks or physical damage.
2. Check for excessive play in control arms and bushings; replace if worn.
3. If struts or shocks are damaged, remove and replace using appropriate tools (socket set, spring compressor).
4. Torque all bolts to specification.

4. Steering Component Inspection

Sub-steps:
1. Check tie rods and ball joints for wear; replace if any play is detected.
2. If a component is worn, disconnect it using a wrench and install a new part, ensuring to torque to the specified values.
3. Recheck alignment after any steering component replacement.

5. Final Check

Sub-steps:
1. Reconnect the battery terminal.
2. Take the vehicle for a test drive to ensure the vibration has been resolved.
3. Monitor for any signs of reoccurring issues.
