IMPORTANT: To help ensure optimum performance, the
drive shaft assemblies are specially balanced as a unit at
the factory. When servicing any flange yoke, slip yoke or
drive shaft tube, order a complete assembly if compo-
nents are bent or damaged. Refer to the appropriate
parts manual for ordering information.
Note: The drive shaft assemblies are balanced assem-
blies. Mark the yoke and transmission, transfer case,
axles, and the shaft and slip yoke so that these compo-
nents can be returned to their original positions when
reinstalled. Yokes at both ends of the drive shaft must be
in the same plane to help prevent excessive vibration.
