DISASSEMBLY
Disassemble in the sequence shown in the figure referring to the disassembly note for specially marked
parts.
Note
a) Clamp the shaft in a vice. Use protectors in the vice to avoid damage.
b)Do not allow dirt or foreign matter in the joint during disassembly or assembly.
c) Do not disassemble the ball-joint at the wheel side. Do not wipe the grease off if there
is no problem.
d)Do not remove the clip used to secure the outer ring to the ball-joint at the differential
side if there is no problem.
If the clip is removed, replace it with a new one.
