lower shaft.) Then install lower
shaft socket over the sphere so
that locating mark on end of upper
shaft is on same side as flat on
lower shaft.
8. Insert the joint preload spring
through centering spheres into
lower shaft. Using the upper shaft
to hold the spring in place and a
screwdriver in the other hand,
carefully feed spring into shaft
joint. See Figure 8-85.
