the figure.
CAUTION:
If there is grease on boot mounting surfaces (indicated by*
marks) of shaft and housing, boot may come off. Remove
all grease from the surfaces.
9. Make sure boot installation length “L” is the length indicated
below. Insert a flat-bladed screwdriver or similar tool into inside
of boot from the large diameter side of boot. Bleed air from boot
to prevent boot deformation.
