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.
