Drive Shaft Disassembly

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.
a. Transfer Case-to-Axle Drive Shafts
1. Use an approved, non-flammable cleaning fluid to
thoroughly clean the drive shaft assembly with a
brush. Wipe dry before disassembling.
CAUTION:
when clamping the drive shaft in a vise. Apply
only enough force to hold the drive shaft
securely. Excessive force can damage the
drive shaft, resulting in an unbalanced
condition.
2. Place the drive shaft assembly in a bench vise.
