Installation

1. Make sure the spindle pin hole in the front axle assembly is free of nicks, burrs, corrosion or foreign material. Clean bore as necessary and lightly coat the surface with a lithium-base grease such as Premium Long-Life Grease XG-1-C or -K or equivalent meeting Ford specification ESA-M1C75-B.

2. Install a new spindle pin seal with the metal backing facing up toward the bushing into the front wheel spindle.

   
   
   
   
   

3. Gently press seal into position; do not distort the casing.

4. Install a new thrust bearing with the lip flange facing down toward the lower bushing.

5. Press until the bearing is firmly seated against the surface of the front wheel spindle.

6. Lightly coat the bushing surfaces with grease and place the front wheel spindle in position on the front axle assembly.

7. Hold the front wheel spindle with thrust bearing tightly in place against the front axle assembly and measure the space between the front axle assembly and the front wheel spindle at the top of the front axle assembly. If the vehicle uses shims, select the proper shims and install.

8. Install the spindle pin with the T stamped on one end toward the top. Align pin notch with lock pin hole in front axle assembly.

9. Insert the spindle pin through the bushings and front axle assembly from the top until the spindle pin notch and axle lock pin hole are aligned.

10. Install the lock pin with the threads pointing forward and the wedge groove facing the spindle pin notch. Firmly drive the lock pin into position and mount the lockwasher and nut. Tighten nut to 50-70 Nm (37-52 lb-ft).

11. Install the spindle pin plugs into the threads at the top and bottom of the front wheel spindle. Tighten the plugs to 48-67 Nm (35-49 lb-ft).

12. Lubricate the spindle pin and bushings with Premium Long-Life Grease XG-1-C or -K or equivalent meeting Ford specification ESA-M1C75-B, through both fittings until grease is visible seeping past the upper seal at the top and from the thrust bearing slip joint at the bottom. If grease does not appear, recheck the installation procedure to correct the problem. Lack of adequate lubrication will result in rapid failure of the spindle components.

13. Install the front disc brake rotor shield. Refer to Section 06-03.

14. Pack the bearing cone and roller and front wheel bearing with bearing grease. Use a bearing packer. If a bearing packer is unavailable, pack the bearing cone by hand working the grease through the cage behind the rollers.

15. Install the bearing cone and roller and wheel hub grease seal. Install the hub and rotor on the front wheel spindle.

16. Install the front wheel bearing, washer and nut. Adjust bearing end play.

17. Install the nut retainer, cotter pin and dust cap.

18. Install the disc brake caliper. Refer to Section 06-03.

19. Connect the steering tie rod and drag link to front wheel spindle, if equipped. Tighten to 75-105 Nm (55-77 lb-ft). Advance the nut as required for installation of the cotter pin.

20. Install the wheel and tire assembly.

21. Lower the vehicle.

22. Check and, if necessary, adjust the toe setting. Refer to Section 04-00. Check the brakes for proper operation.
