Rear Assembly

7. Measure torque to rotate the pinion with an inch-

pound torque wrench. Torque measurements should
be taken every fourth (4th) revolution and should
read between 34-42 in.lbs. of bearing preload.

Note: If bearing preload does not fall within allowed limits,

preload can be increased by using a thinner spacer and
decreased by using a thicker spacer.

Always measure each spacer before assembly to
ensure correct thickness.

8. Repeat process until torque to rotate is between 34-

42 in. lbs. After proper preload is achieved, remove
yoke and install new seal with proper service tool.

CAUTION:
Do not use any silicone or permatex-type bore sealant with
this seal.

9. Remove the new seal from its package and install

with the proper driver:
R-Pinion-Use drive #126917 only

WARNING:
Due to the resiliency of the plastic driver, hammer rebound
may occur when the seal is seated. Keep clear of the hammer
rebound path!

10. Handle the seal by its outside diameter avoiding any

contact with the seal lips. During installation, use the
proper driver to make sure that the seal is mounted
properly.

11. Use a rubber mallet to drive the seal tool in until the

flange bottoms on the housing cover bore face. The
flange will locate the seal at the proper depth.

12. Install end yoke.

Note: Dana Spicer recommends that new torque prevailing

nuts be used.

13. Use torque multiplier and torque pinion nut to 710-

1040 lbs. ft. (848-1410 N•m).
