Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Suspension Components

Inspect Suspension:
- Use a jack to lift the vehicle and secure it with jack stands.
- Visually check the struts and shocks for leaks or physical damage.
- Look for worn or cracked bushings on control arms and sway bars.
Replace Worn Components:
- If any components are damaged, remove them:
  - Use a socket set to unbolt the struts or shocks from their mounts.
  - Remove sway bar links if they are worn.
- Install new struts or shocks:
  - Ensure proper alignment with mounting points.
  - Torque bolts to manufacturer specifications (typically around 30-50 ft-lbs for struts).
- Replace any bushings with new ones:
  - Use a bushing press if necessary for installation.

3. Reassemble and Lower Vehicle

Reattach any removed components and verify all nuts and bolts are secured.
Remove jack stands and lower the vehicle to the ground.
Reconnect the battery.
