Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, pry bar, and flashlight.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Lift the Vehicle

Use the jack to lift the vehicle at the designated jacking points.
Secure the vehicle with jack stands to ensure safety while working underneath.

3. Inspect and Replace Worn Components

Suspension Components:
- Check struts and shocks for leaks or damage. If defective, remove and replace them.
  - Sub-steps:
    1. Use the socket set to remove the bolts securing the strut/shock to the control arm and top mount.
    2. Install the new strut/shock, aligning it properly and tightening the bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).
Sway Bar Links and Bushings:
- Inspect and replace if worn.
  - Sub-steps:
    1. Remove the nuts from the sway bar link using a socket.
    2. Replace the link and/or bushings, ensuring all connections are tight.

4. Reassemble and Lower Vehicle

Reinstall any components removed for inspection.
Lower the vehicle back to the ground and remove jack stands.

5. Final Check

Inspect all fasteners and components for proper fit and tightness.
Ensure that no tools are left under the vehicle.
