REMOVAL
NOTICE:
The hub bearing could be damaged if it is subjected
to the vehicle weight, such as when moving the ve-
hicle with the drive shaft removed.
Therefore, if it is absolutely necessary to place the ve-
hicle weight on the hub bearing, first support it with
the SST.
SST 09608±16042 (09608±02021, 09608±02041)
After disconnecting the drive shaft from the axle hub,
work carefully so as not to damage the ABS speed
sensor rotor serrations on the drive shaft.

HINT:
At the time of installation, please refer to the following items.
Apply gear oil to the inboard joint shaft and differential
case sliding surfaces.
Before installing the drive shaft, set the snap ring with its
opening side facing downward.
Whether inboard joint shaft is in contact with pinion shaft
or not can be known from the sound or feeling.
After installation, check that there is 2 ± 3 mm (0.08 ± 0.12
in.) of play in the axial direction.
After installation, check that the drive shaft cannot be re-
moved by hand.
