Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

Use a floor jack to lift the front or rear of the vehicle, placing jack stands under the frame for safety.
Ensure the vehicle is stable before working underneath it.

3. Inspect and Replace Worn Components

Check Struts/Shocks:
- Remove the bolt securing the strut/shock to the lower control arm using a socket wrench.
- Inspect for leaks or damage; if damaged, replace with OEM struts/shocks.
Inspect Control Arms:
- Check for play in the control arm bushings; replace if they show excessive wear.
- Remove the control arm bolts and replace the bushings if necessary.
Check Sway Bar Links:
- Inspect sway bar links for looseness or wear; replace if damaged.
- Remove the nuts securing the sway bar links and replace with new links.

4. Reassemble and Lower the Vehicle

Reattach all components securely and torque bolts to manufacturer specifications.
Lower the vehicle from the jack stands and remove the jack.

5. Conduct a Final Inspection

Double-check all fasteners and components for tightness.
Ensure there are no visible issues or obstructions in the suspension system.
