3. If the bearing assembly will not pull out by hand after

pressing, tap the base of the lug near the bearing
assembly to dislodge it.

spider hole.  If the spider or bearing are cocked, the
bearing will score the walls of the spider hole and ruin
the yoke.

remove the spider from the yoke.

6. Make sure of proper position for reinstallation by

applying setting marks, then remove spider .
