- Install new sway bar links and tighten bolts to the specified torque.
Control Arms/Bushings:
- If control arm bushings are worn, remove the control arm by unbolting it from the vehicle.
- Press out the old bushings and install new ones using a bushing removal tool.
- Reinstall the control arm and torque the bolts to specifications.
