5.4.2 Drive Shaft Maintenance
Refer to the appropriate owners/operators manual for
information regarding the lubrication of the grease fittings
on the drive shafts.
5.4.3 Drive Shaft Removal
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
components are bent or damaged. Refer to the appropriate
parts manual for ordering information.
Note: The drive shaft assemblies are balanced
assemblies. Mark the yoke and axle, transmission,
transfer case, and the shaft and slip yoke so that these
components 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.
