This may be the suggestion from the manual, but that method works only 
if the bearing races are completely and fully seated.

For a long time, whenever doing a rebuild of the front bearing, I've 
used the following procedure:  drive the outer races home, fully grease 
the new bearings, then assemble and without allowing the wheel to turn, 
torque the bearing retainer nut to about 50 lb/ft. Then slack off the 
bearing retainer nut and adjust the free play according to the manual.

This ensures that everything is in place as it should be before setting 
free play. The races and bearings will tolerate the load without 
deformation, as long as there's no attempt to turn the wheel while 
compressed, and the felt seal will be compressed adequately to present 
no problems later.

Cheers.
