Propeller Shaft
General Description

Legend
(1) Front Propeller Shaft
(2) Rear Propeller Shaft;
Aluminum Tube with Spline Yoke Type(3) Rear Propeller Shaft;
Aluminum Tube with Flange Yoke Type
(4) Rear Propeller Shaft;
Steel Tube Type (for 4y4, 6VD1, A/T model)
Torque is transmitted from the transmission to the axle
through the 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 balanced carefully,
welding or any other modification is not permitted.
Alignment marks should be applied to each propeller
shaft before removal.

Park, turn the engine off and apply the parking brake
to secure the vehicle.

Carefully attach the propeller shaft to the vise, do not
overtighten the vise when securing the propeller
shaft, this may cause deformation.

Phasing
The propeller shaft is designed 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 will absorb vibrations
from speeding up and slowing down each time the
universal joint spins.This vibration would be the same as
a person snapping a rope and watching the ºwaveº
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 ºwavesº 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.
Universal Joint
401RW015
Legend
(1) Spider
(2) Yoke
A universal joint consists of two Y-shaped yokes
connected by a crossmember called a spider.
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. Within the
designed angle variations, the universal joint will operate
efficiently and safely. When 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 in the yokes by snap rings.
