6. Measure pinion torque to rotate (1) with an inch pound torque wrench (2). Pinion torque to rotating 

should be equal to recorded reading plus an additional 0.56 N.m (5 in. lbs.). 

If pinion torque to rotate is low, tighten pinion nut in 6.8 N.m (5 ft. lbs.) increments until pinion torque to 
rotating is achieved. 

CAUTION: Never loosen pinion nut to decrease pinion bearing rotating torque. If 

pinion torque to rotating is exceeded, a new collapsible spacer must 
be installed. Failure to follow these instructions will result in damage 
to the axle.
