f.
Tilt inner race (5) in outer race (6) until one ball
(7) can be removed, continue this procedure
until all balls (7) are removed. A soft faced
hammer may be used to aid inner race (5)
movement.
g.
Roll universal joint cage (8) at a right angle to
universal joint outer race bell (6) with the two
elongated openings in cage (8) aligned with
opposite teeth of outer race bell (6). Lift cage

h.
Inspect axle shaft and universal joint assembly
for seizure, broken or chipped balls, broken
splines or other damage.
i.
Inspect spindle bushing for out of round
condition caused by wear or corrosion, scoring
or roughness in spots.
j.
Inspect axle shaft oil seal for evidence of wear
or damage.
k.
Inspect for evidence of wear due to improper
drive flange shim size. Wear on the interior
surface of ball end of axle housing and on edge
of ball joint bell housing indicates the use of too
thin a shim, allowing contact between the two.
If shim is too thick, the spindle bushing will
show excessive wear.
