- Torque bolts to manufacturer specifications (typically around 30-50 ft-lbs).
Sway Bar Links:
- Remove the nuts securing the sway bar links to the sway bar and control arm.
- Replace with new sway bar links.
- Torque to manufacturer specifications.
Control Arms and Bushings:
- Remove the bolts securing the control arms.
- Inspect bushings for cracks or excessive wear; replace as necessary.
- Reinstall control arms and torque bolts to specifications.
