SHAFT WITH INNER SHAFT
CONNECTION/DRIVE SHAFT INSTALLATION
Temporarily install the drive shaft so that the inn er shaft or
T.J. case of the drive shaft is to the transaxle.
Caution
Do not damage the oil seal lip by the serrated part of
the drive shaft.
DRIVE SHAFT NUT INSTALLATION
(1) Install the drive shaft washer in the specified direction.
(2) Use the
tool to tighten the drive shaft nut.
Caution Before securely tightening the drive shaft nuts, ma ke
sure there is no load on the bearings.
(3) If the position of the cotter pin holes does no t match,
tighten the nut up to 255 Nm (188
in maximum.
(4) Install the cotter pin in the first matching ho les and bend
it securely.
