2. Inspect and Replace Worn Components

Inspect Suspension Components:
- Visually check struts and shocks for leaks or damage.
- Examine control arms for cracks or excessive wear.
Replace Worn Struts/Shocks:
1. Raise the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
2. Remove the Wheel: Use a socket set to remove the lug nuts and take off the wheel for access.
3. Detach the Strut/Shock: Remove the bolts securing the strut/shock to the control arm and the top mount.
4. Install New Strut/Shock: Position the new strut/shock into place, secure it with bolts, and torque them to the manufacturer's specifications.
5. Reinstall the Wheel: Replace the wheel and lug nuts, then lower the vehicle.

3. Replace Sway Bar Links and Bushings

If sway bar links or bushings show wear:
1. Remove Old Links/Bushings: Use a socket set to detach the sway bar links from the sway bar and control arm.
2. Install New Links/Bushings: Position new sway bar links and bushings, securing them with the appropriate bolts and torque specifications.
