Solution

1. Preparation

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

2. Raise the Vehicle

Using a jack, lift the vehicle and place it securely on jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Components

Sway Bar Links:
- Remove the lower bolt securing the sway bar link to the control arm using the socket set.
- Inspect the link for wear; if damaged, replace with a new sway bar link.
Control Arm Bushings:
- Use a pry bar to check for play in the control arm bushings.
- If worn, remove the control arm by unbolting the bolts securing it to the chassis and the ball joint.
- Replace the bushings if necessary and reinstall the control arm, ensuring bolts are torqued to manufacturer specifications.
Struts:
- Check for leakage; if leaking, remove the strut assembly by unbolting the top and bottom mounts.
- Replace the strut with a new unit and ensure proper alignment of the mounting holes.

4. Reassemble and Lower Vehicle

Reinstall any components removed for inspection or replacement.
Ensure all bolts are tightened to the manufacturer's torque specifications.
Carefully lower the vehicle off the jack stands.
