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.

Check for any deformation of the boot installation components.

as shown.
CAUTION:
If there is grease on boot mounting surfaces (indicated by*
marks) of shaft and housing, boot may come off. Remove
all grease from surfaces.
9. Check that the boot installation length “L” is the specified length.
Insert a flat-bladed screwdriver or similar tool into bigger side of
boot. Bleed the air from the boot to prevent any boot deforma-
tion.
