REAR AXLE ± General Information27-2
GENERAL INFORMATION27100010118

The rear axle is a banjo-type semi-floating type.
The axle shaft bearings are: *Single taper
bearings for vehicles without ABS or rear
differential lock. *Double-taper bearings for
vehicles with ABS or rear differential lock. ABS
rotor is press-fitted to the axle shaft retainer
ring.
Differential gear has 4 different types. A
torque-responsive mechanical-type limited slip
differential has a high performance against
driving on unstable surfaces such as muddy
roads.

Driveability on sand or muddy road has been
improved, and rear differential lock, which is
useful for emergency , has been used.
