Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, and a flashlight.
Ensure the vehicle is on a flat surface and the engine is off. Engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Make sure to position the jack stands under the designated lift points to ensure safety.

3. Inspect and Replace Suspension Components

Check Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Inspect for oil leaks and physical damage. Replace if necessary.
Inspect Bushings:
- Use a pry bar to check the condition of the control arm bushings and sway bar links.
- If bushings are cracked or worn, remove the old bushings and install new ones.
Check Mounts:
- Inspect strut mounts for wear. If they show signs of damage, replace them by removing the strut assembly and installing new mounts.

4. Reassemble and Torque

Reinstall the wheel and ensure all hardware is tightened to the manufacturer's specifications.
Use a torque wrench to apply the correct torque to lug nuts (typically around 80-100 ft-lbs for most Honda models).

5. Lower the Vehicle

Carefully lower the vehicle back to the ground and remove the jack stands.
