Remove: Use a socket set to remove the bolts connecting the sway bar links to the sway bar and lower control arm.
Inspect: Check for play in the links; replace if damaged.
Install: Attach the new sway bar links, tightening to manufacturer specifications (consult repair manual for torque values).

B. Struts/Shocks

Remove: Unbolt strut assembly using a socket set and remove any retaining clips.
Inspect: Check for oil leakage or physical damage.
Install: Replace with new struts or shocks, securing all bolts to the specified torque.

C. Control Arms

Remove: Detach the control arm by unscrewing the bolts.
Inspect: Examine bushings for cracks or excessive wear.
Install: Replace any worn control arms and bushings, ensuring proper alignment and torque specifications.

4. Reassemble and Lower Vehicle

Reattach all components and ensure all bolts are tightened to manufacturer specifications.
Lower the vehicle carefully off the jack stands.
