GENERAL INFORMATION
REAR AXLE27-2
GENERAL INFORMATION
M2270000100382
The rear axle has the following features:
•The wheel bearing is a unit ball bearing (dou-
ble-row angular contact ball bearing) for reduced
friction.
•The wheel bearing incorporates magnetic
encoder for wheel speed sensing.
•The rear wheel hub assembly combines the hub,
wheel bearing and oil seal in a single unit for
fewer parts, better durability, improved assembly
precision, and better structural organization.

Newly developed H-shaped torsion beam type sus-
pension has been introduced.
•The coil spring is installed under the rear floor,
the torsion beam and arm assembly is installed in
front of the spare tyre house, and the shock
absorber is installed outside, so that the large
cabin space is achieved.
•The arm bushing with the toe control function is
adopted to optimise the tyre steering angle using
the bushing deflection caused by lateral force
and longitudinal force generated at cornering, so
that the good cornering performance is secured.
•The layout of shock absorber is optimised for
smooth riding.
•Long wheel stroke secures sufficient road holding
quality.
•The hub-integrated unit bearing is adopted for the
wheel bearing for sufficient suspension rigidity
(Refer to GROUP 27, Rear Axle
P.27-2).
•The dumping characteristic of shock absorber
has been changed. <4G1>
•The urethane bump stopper has been adopted to
improve the linearity. <4G1>
•Torsion beam rigidity has been improved <4G1>

GENERAL INFORMATION
FRONT AXLE26-2
GENERAL INFORMATION
M2260000100701
The front axle consists of front hub, wheel bearing,
knuckles and driveshafts, and has the following fea
-
tures:
•The wheel bearing incorporates magnetic
encoder for wheel speed sensing.
•The driveshaft incorporates EBJ-TJ type constant
velocity joint <4A9-CVT, 4A9-M/T (LS)>,
EBJ-ETJ type constant velocity joint <4A9-M/T
(VR)>, BJ-TJ type constant velocity joint <4G1>.
•The dynamic damper is mounted to reduce differ-
ential gear noise.
•The bracket assembly is mounted to reduce
torque steer. < 4G1>
•For environmental protection, a lead-free grease
is used on the joints.
EBJ(Eight Ball Fixed Joint):The use of the
smaller-sized eight balls inside the joint achieves
weight saving and compact size compared with a
BJ(Birfield Joint).
ETJ(Eco type Tripod Joint):This joint achieves
weight saving and compact size compared with a
TJ(Tripod Joint).
