Torque is transmitted from the transmission to the
axle through propeller shaft and universal joint
assembles. All propeller shafts are the balanced
tubular type. A splined slip joint is provided in some
drivelines.

Since the propeller shaft is total balanced carefully,
welding or any other modification are not permitted. 
Alignment marks should be applied to each
propeller shaft before removal.

Be sure vehicle is stopped, engine is not running,
brake is secured and vehicle is secured to prevent
injury.

Be careful not to grip the propeller shaft tube too
tightly in the bise as this will be cause deformation.

Removal and Installation

401RS023
Removal
1. Raise the vehicle on a hoist.
NOTE:
Apply alignment marks on the flange at the rear
propeller shaft both front and rear side.


2. Remove center bearing fixing bolt.
3. Remove rear axle side bolt, nut and washer.
4. Remove rear propeller shaft.

NOTE:
Plug the hole of the transmission rear end to prevent oil
leakage.

401L100007
Installation
NOTE:
Cover the slip yoke with cloth to avoid damage to the oil seal
contact surface, when removing propeller shaft from
transmission. Do not damage the oil seal contact surface of
slip yoke with other parts at removal and installation.
Completely remove the dust or foreign matter from the
connecting surface of flange coupling on each end of the
propeller shaft.

1.
Align the mark which is applied at removal and insert the
propeller shaft in the transmission.
2. Install rear propeller shaft and tighten the bolts to the
specified torque.

REAR AXLE 4B-7

REAR AXLE ASSEMBLY
General Description
A03R300001

The rear axle assembly is of the semi–floating type in
which the vehicle weight is carried on the axle
housing .
The center line of the pinion gear is below the center
line of the ring gear (hypoid drive).
All parts necessary to transmit power from the
propeller shaft to the rear wheels are enclosed in a
banjo type axle housing.
The 220 mm (8.6 in) ring gear rear axle uses a
conventional ring and pinion gear set to transmit the
driving force of the engine to the rear wheels. This
gear set transfers this driving force at a 90 degree
angle from the propeller shaft to the drive shafts.
The axle shafts are supported at the wheel end of the
shaft by a double tapered roller bearing.
The pinion gear is supported by two tapered roller
bearings. The pinion depth is set by a shim pack
located between the gear end of the pinion and the
roller bearing that is pressed onto the pinion. The
pinion bearing preload is set by crushing a collapsible
spacer between the bearings in the axle housing.
The ring gear is bolted onto the differential cage with
12 bolts.
The differential cage is supported in the axle housing
by two tapered roller bearings. The differential and ring
gear are located in relationship to the pinion by using
selective shims and spacers between the bearing and
the differential cage. To move the ring gear, shims are
deleted from one side and an equal amount are added
to the other side. These shims are also used to
preload the bearings which are pressed onto the
differential cage. Two bearing caps are used to hold
the differential into the rear axle housing.
The differential is used to allow the wheels to turn at
different rates of speed while the rear axle continues
to transmit the driving force. This prevents tire
scuffing when going around corners and prevents
premature wear on internal axle parts.
The rear axle is sealed with a pinion seal, a seal at
each axle shaft end, and by a liquid gasket between
the differential carrier and the axle housing
