Use a hydraulic jack to lift the vehicle.
Secure with jack stands to ensure stability.

3. Inspect and Replace Worn Components

Control Arms and Bushings:
- Remove the wheel to access the suspension components.
- Inspect control arms and bushings for cracks or excessive wear.
- If worn, remove the control arm bolts using a socket set.
- Replace with new control arms and bushings.
Sway Bar Links:
- Check the sway bar links for play or damage.
- If damaged, remove the sway bar link bolts and replace with new ones.

4. Tighten Loose Bolts

Use a torque wrench to ensure all suspension bolts are tightened to the manufacturer's specifications.
