  7. Tighten
    Tighten the bolts to 145 N·m (110 Ib ft).

    Important: When tightening the lower ball stud nut, a minimum torque of 50 N·m (37 Ib ft) must be obtained. If 50 N·m (37 Ib ft) is not obtained, inspect for stripped threads. If threads are satisfactory, replace the ball joint and the knuckle.

  8. Install both lower ball joints into the steering knuckles and both ball joint nuts and cotter pins.
  9. Tighten

    1. Tighten the ball joint nut to 10 N·m (84 Ib in) using J 35551 and a torque wrench.
    2. Tighten the nut an additional 120°.
    3. If required, turn the nut up to an additional 60° in order to allow for installation of the cotter pin.

    Important: When tightening the tie rod end nut, a minimum torque of 45 N·m (33 Ib ft) must be obtained. If 45 N·m (33 Ib ft) is not obtained, inspect for stripped threads. If threads are satisfactory, replace the tie rod end and the knuckle.

  10. Install both tie rods into the steering knuckles and both tie rod nuts and cotter pins.
  11. Tighten

    1. Tighten the nuts to 10 N·m (7.5 Ib ft ) then an additional 1/3 turn (2 flats).
    2. After tightening the castellated nut to specification, align the slot in the nut to the cotter pin hole by tightening only. Do not loosen the nut for cotter pin installation.
  12. Install both stabilizer links to the struts.
  13. Tighten
    Tighten the nuts to 65 N·m (49 Ib ft ).

  14. Install both front suspension position sensors to the lower control arms.
  15. Install both front wheel opening splash shields.
