5. Tighten the mounting bolts to the manufacturer's specified torque value.

3. Replace Worn Sway Bar Links

Sub-steps:
1. Locate the sway bar links connected to the sway bar and lower control arm.
2. Use a wrench to remove the bolts securing the sway bar links.
3. Inspect the bushings for wear, and if damaged, replace them along with the sway bar links.
