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.


Phasing
The propeller shaft is designer and built with the yoke lugs
(ears) in line with each other. This design produces the
smoothest running shaft possible, called phasing. Vibration can
be caused by an out-of-phase propeller shaft. The propeller
shaft down each time the universal joint goes around. This
vibration would be the same as a person snapping rope and
watching the “wave” reaction flow to the end. A propeller shaft
working in phase would be similar to two persons snapping a
rope at the same time, and watching the “waves” meet and
cancel each other out. In comparison, this would be the same
as the universal joints on a propeller shaft. A total cancellation
of vibration produces a smooth flow of power in the driveline. It
is very important to apply a reference mark to the propeller
shaft before removal, to assure installation alignment.

401RW 015
Universal Joint
A universal joint consists of two Y-shaped yokes (2) connected
by a crossmember called a spider (1).
The spider is shaped like a cross. Universal joints are designed
to handle the effects of various loadings and front or rear axle
windup during acceleration. W ithin the designed angle
variations, the universal joint will operate efficiently and safely.
W hen the design angle is changed or exceeded the
operational life of the joint may decrease.
The bearings used in universal joints are of the needle roller
type. The needle rollers are held in place on the trunnions by
round bearing cups. The bearing cups are held inside the
yokes by snap rings.

Diagnosis of Propeller Shaft and
Universal Joint

Condition Possible cause Correction
Rough surface on splined yoke;
burred nicked or worn. Replace the seal. Minor burrs can
be Smoothed by careful use of
crocus cloth or fine stone honing.
Replace the yoke if badly burred. Leak at the Front Slip Yoke (An
Occasional Drop of Lubricant
Leaking from the Splined Yoke is
Normal)
Defective transmission rear oil seal. Replace the transmission rear oil seal and replenish the transmission
oil.
W orn universal joint bearings. Replace.
Improper lubrication. Lubricate as directed.
Universal Joint Noise.
Loose flange bolts. Tighten to specifications.
Loose bushing bolts on the rear
springs or upper and lower control
arms. Tighten the bolts to specified
torque. Ping, Snap, or Click in Drive Line
(Usually Heard on Initial Load after
the Transmission is in Forward or
Reverse Gear) Loose or out-of-phase end yoke. Remove end yoke, turn 180
degrees from its original position,
lubricate the splines and reinstall.
Tighten the bolts and pinion nut to
specified torque.
Squeak Lack of lubricant. Lubricate joints and splines. Also
check for worn or brinelled parts.
Loose or missing bolts at the
flanges. Replace or tighten bolts to specified
torque.
Incorrectly set front joint angle. Install shim under the transmission support mount to change the front
joint angle.
Shudder on Acceleration (Low
Speed)
W orn universal joint. Replace.
Incorrect shaft runout. Replace.
Shaft out of balance. Adjust.
Transmission rear housing bushing,
transfer case housing bushing worn. Replace.
Vibration
Yoke spline jammed. Replace.

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.

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.

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 cente
r
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 φ220 mm (8.6 in) or φ194mm (7.6 in) ring gea
r
rear axle uses a conventional ring and pinion gear set
to transmit the driving force of the engine to the rea
r
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 rolle
r
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.
