3. Stake nose of pinion in 6 places, using a center

punch or equivalent tool.

See Figure 7.

4. Install inner pinion bearing cup into pinion bearing

cage.

5. Install outer pinion bearing cup into pinion bearing

cage.

6. Use a feeler gauge or shim stock (.0015 Approx.) to

ensure bearing cups are completely seated in
bearing bores. This is necessary for proper pinion
position.

7. Place pinion bearing spacer, that was removed during

disassembly, onto pinion.

8. Place pinion bearing cage onto inner pinion bearing

cone.

9. Install outer pinion bearing cone and washer on to

pinion.

10. Inspect end yoke or flange for grooves in seal

surface caused by contaminants. If grooves can
be detected with fingernail, then end yoke must be
repaired with a CR approved repair sleeve replaced.

11. Install end yoke onto pinion without seal, to allow

proper setting of bearing preload. Torque pinion nut
to 700-900 Lb-Ft (950-1,220 N-m)
