CLEANING AND INSPECTION (OUTER)
Wash all metallic parts thoroughly in a cleaning
solvent. Dry with compressed air. Rubber seal must
be replaced whenever C.V . joint is disassembled for
service.
NOTE : Outer and inner race may show a definite
polished area where the balls travel . The C.V .
joint should not be replaced for this reason .
However, if this wear pattern is suspected to be
the cause of a noisy or vibrating C .V . joint, the
joint should be replaced .
1 . Inspect outer race for excessive wear or scoring
in the ball grooves. Inspect shaft splines and threads
for damage .
2. Inspect balls (six) for nicks, cracks, breaks or
scores .

4. Inspect inner race for excessive wear, scores or
breaks .
5. Inspect retaining ring for breaks .
NOTE : If any of the above defects, except Item
