These cradle nuts, tighten them to 135 nm (96 lb ft), do the same for the power steering gear retaining bolts 180 nm (133 lb ft). Reinstall the lower Control Arm to steering knuckle nut, tightening it 40 nm (30 lb ft), and an additional 120 degrees. Reassemble the abs wire harness and the stabilizer shaft link; fasten the lower retaining nut to 115 nm (95 lb ft). Link the shock module yoke with the lower Control Arm, the air deflector, and the tire and wheel. Lastly, depress the vehicle and carry out front end alignment.
