INSPECTION AFTER DISASSEMBLY
Drive Shaft
Replace the drive shaft if there is any runout, cracking, or other damage.
Joint Sub-assembly
Check for any rough rotation or unusual axial looseness.
Clean any foreign material from inside the joint sub-assembly.
Check for any compression scars, cracks, or fractures.
CAUTION:
If any defective conditions are found in the joint sub-assembly components, replace the entire
joint sub-assembly.
Sliding Joint Side Housing
Check for any compression scars, cracks, fractures, or unusual wear on the ball rolling surface.
Check for any damage to the drive shaft screws.

8. Check that the boot installation length “L” is the length indicated below. Insert a suitable tool into the large end of the boot, as
shown. Bleed air from the boot to prevent boot deformation.
CAUTION:
The boot may break if the boot installation length is less than the specified value.
Do not contact inside surface of boot with tip of the suitable tool.
9. Secure the large and small ends of the boot with the new boot bands as shown.
NOTE:
