DISASSEMBLY
1. CHECK DRIVE SHAFT
(a) Check that operation of the joint is smooth within the slid-
ing region in the axial direction.
HINT:
If a large angle is used for the cross±groove type joint, the joint
will feel like it is catching, but this does not indicate an abnormal-
ity.
(b) Check that the boots are not cracked, damaged or leak-
ing.
(c) Check that there are no scratches on the speed sensor
rotor.
2. REMOVE END COVER
(a) Using a screwdriver, remove the end cover.
(b) Use bolts, nuts and washers to keep the inboard joint to-
gether.
NOTICE:
Tighten the bolt by hand to avoid scratching the flange sur-
face.
3. REMOVE BOOT CLAMPS
Using a side cutter or pliers, remove the 4 boot clamps.
4. REMOVE INBOARD JOINT
(a) Place matchmarks on the inboard joint and drive shaft.
NOTICE:
Do not puch the marks.

2. ASSEMBLE INBOARD JOINT
If the joint has come apart, reassemble it in the following order.
(a) Align the matchmarks placed before removal.
HINT:
When the matchmarks have disappeared, do the following pro-
cedure.
(1) Install the inner race to the cage so that the in-
dented bevelled part of the inner race is on the op-
posite side to the bevelled top of the cage.
(2) Install the outer race so that the indented side of the
outer race is facing the same side as the bevelled
surface of the cage.
(3) Match the narrow projections of the inner race with
the wide projections of the outer race.
(b) Tilt the cage and inner race to the side and insert the balls
one by one.
NOTICE:
When the cage and inner race are tilted over, support the
joint with your hand to prevent the balls from falling out.
3. TEMPORARILY INSTALL NEW BOOTS AND NEW
BOOT CLAMPS
