PROCEDURE

NOTICE
The new nut is torque sensitive. Retention capability of an old nut removed from the vehicle may not be sufficient if reused. Therefore, a new nut must be used any time the nut is removed.

When servicing the outer tie rod-to-steering knuckle joint on vehicles equipped with torque prevailing nuts, the procedure for new nut installation is as follows:

1. If outer tie rod is being replaced, thread new outer tie rod onto inner tie rod.





2. Install outer tie rod stud into steering knuckle joint.

3. Install steering linkage installer (J-44015), or equivalent on outer tie rod stud.

4. Torque steering linkage installer to properly seat outer tie rod into steering knuckle joint.

Torque: 45 N.m (33 ft-lbs)





5. Remove steering linkage installer and install a new torque prevailing nut

6. Tighten new torque prevailing nut.

Torque: 25 N.m (18 ft-lbs)

7. Install torque angle gauge P/N SA9140E, Snap-On Tool 360, or equivalent tool.

8. Calibrate gauge to zero.

9. Tighten nut an additional 134 degrees.
