Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Shock Absorbers/Struts

Lift the Vehicle: Use a floor jack to lift the vehicle and secure it on jack stands.
Remove the Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Disconnect the Shock Absorber:
- Remove the bolts securing the shock absorber to the lower control arm.
- Remove the top mounting bolts from inside the engine compartment or trunk.
Install New Shock Absorber:
- Position the new shock absorber in place and secure it with the top and bottom bolts.
- Torque bolts to manufacturer specifications (consult service manual).
Reinstall Wheel: Place the wheel back on and hand-tighten the lug nuts.

3. Inspect and Replace Sway Bar Links/Bushings

Access the Sway Bar: With the vehicle still lifted, locate the sway bar.
Remove Old Links: Use a wrench to remove the bolts securing the sway bar links to the sway bar and lower control arm.
Install New Links: Position new sway bar links in place and secure with bolts.
Check Bushings: If bushings are worn, remove the sway bar and replace the bushings before reinstalling.
