3 - 8 PROPELLER SHAFTS
SERVICE PROCEDURES (Continued)
Fig. 12 Propeller Shaft Angle Measurement (C)
1 – SHAFT YOKE BEARING CAP
2 – SPECIAL TOOL 7663 (J23498–A)
(5) Rotate propeller shaft 90 degrees and place
Inclinometer on pinion yoke bearing cap parallel to
the shaft (Fig. 13). Center bubble in sight glass and
record measurement.
This measurement will give you the pinion
shaft or input yoke angle (B).
Fig. 13 Rear (Input) Angle Measurement (B)
1 – PINION YOKE BEARING CAP
2 – SPECIAL TOOL 7663 (J-23498A)
(6) Subtract smaller figure from larger (C minus
B) to obtain axle Input Operating Angle.
Refer to rules given below and the example in for
additional information.
• Good cancellation of U–joint operating angles
(within 1°).
• Operating angles less than 3°.
• At least 1/2 of one degree continuous operating
(propeller shaft) angle.
TWO-PIECE PROPELLER SHAFT
The procedure to measure the propeller shaft
angles involved with a two-piece propeller shaft is
the same as those for a one-piece propeller shaft. The
following additional conditions also apply:
• The front half-shaft must be parallel to the rear
axle pinion shaft.
• The front and rear half-shafts must be offset by
a minimum of 1/2 of a degree. From the transmis-
sion/transfer case output shaft and from each other.
• Excessive variation in measurement angles of A,
B or C indicate propeller mis-alignment.
• Vertical alignment of a two-piece shaft at the
yokes should be greater than one-half degree and as
close to one degree as possible.
REMOVAL AND INSTALLATION
FRONT PROPELLER SHAFT
REMOVAL
(1) Shift the transmission and transfer case to
their neutral positions. Raise and support vehicle.
Remove skid plate, if equipped.
(2) Using a suitable marker, mark a line across
the yoke at the transfer case, the link yoke, and pro-
peller shaft yoke at the rear of the front propeller
shaft for installation reference.
(3) Mark a line across the propeller shaft compan-
ion yoke and flange at the front axle for installation
reference.
