- Torque bolts to manufacturer specifications (check service manual for exact values).
Sway Bar Links/Bushings:
- Remove the sway bar link using a socket set.
- Inspect the bushings for wear; replace if they appear cracked or soft.
- Install new sway bar links and bushings as necessary, ensuring proper torque.

4. Reassemble Vehicle
