Inspect Struts/Shocks:
- Remove the wheel to access the suspension components.
- Check for signs of wear or damage on struts and shocks. If damaged, replace them.
Replace Sway Bar Links:
- Locate the sway bar links and check for play or damage.
- Remove the bolts securing the sway bar links using a socket set.
- Install new sway bar links and torque to manufacturer specifications.
Examine Bushings:
- Check the condition of bushings attached to control arms and sway bars.
- If cracked or worn, remove the old bushings and press in new ones.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and tighten lug nuts to manufacturer torque specifications.
Carefully lower the vehicle back to the ground.
