RTW 64ASF000101
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 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.
