Service Procedure: Propeller Shaft Replacement
Replace the propeller shaft per service manual procedures:
* Driveshaft and axle > Front Propeller Shaft Assembly > Propeller Shaft
Perform a test drive to confirm if vibration is resolved. If the vibration is not resolved, continue to the
propeller shaft angle inspection service procedures below.

Service Procedure: Propeller Shaft Angle Inspection
▶ PROTRACTOR (digital inclinometer)
USAGE
Bottom surface of protractor is magnetic.
To initialize angle measurements, set the
protractor against a reference surface.
When the reference position is set, press
the All Zero button to set to zero (0).
Arrows indicate positive or negative angles.
IMPORTANT
Orientation of the protractor affects the
measurement reading.
Always orient the protractor so
that the LCD display can be read
from the DRIVER’S SIDE of the
vehicle.
This will ensure that positive (+)
measurements (UP arrow) will be
consistent with the definitions in this TSB.

▶ PROPELLER SHAFT ANGLE DEFINITIONS
IMPORTANT
The propeller shaft angles Θ1 and Θ2 are defined as follows:
(Θ1): Angle Between Engine/Trans To Front Shaft Section
(Θ2): Angle Between Front and Rear Shaft Sections
(A): Protractor Angle Measurement Position
PLEASE NOTE Θ1 and Θ2 have different reference positions. This means the protractor
must be zeroed on the transmission for Θ1, and then re-zeroed on the front of the propeller
shaft for Θ2.
Angle Specifications (degrees) are shown below. If the measured angles are not within these
specifications, washers must be installed to adjust the angles to specifications, as described
in the service procedures below.
Propeller Shaft Angle Specifications:
Θ1: -0.6 to 0.4
Θ2: -0.3 to 0.7
*** The Θ1 angle directions are positive (+) when the front portion of the propeller shaft
slopes downwards (front to back) when compared to the transmission, and negative (-) when
the front portion of the propeller shaft slopes upwards.
*** The Θ2 angle directions are positive (+) when the rear portion of the propeller shaft slopes
downwards (front to back) when compared to the front portion of the propeller shaft, and
negative (-) when the rear portion propeller shaft slopes upwards.

▶ Measure (Θ1): Angle Between
Engine/Trans To Front Shaft Section
After setting the zero (0.0) reference
angle at the transmission flange, move
the protractor to the front portion of the
propeller shaft.
Verify the protractor is positioned
properly on the propeller shaft, with the
length of the protractor parallel to the
propeller shaft tube, and the protractor
body pointed at a right angle to the
ground.
3b.
Refer to the image to the right.
After properly positioning the protractor,
check the angle measurement reading
on the display and record the value. Do
not move the protractor.

Move the protractor to the rear section of
the propeller shaft.
Verify the protractor is positioned
properly on the propeller shaft, with the
length of the protractor parallel to the
propeller shaft tube, and the protractor
body pointed at a right angle to the
ground.
Refer to the reference image on the right.

5.
If required, install washers to adjust angles Θ1 and Θ2 to specification.
If the greatest angle change needed is to adjust Θ2 in the negative (-) direction, follow the
procedures described in Case 1 below.
If the greatest angle change needed is to adjust Θ1 in the positive (+) direction, follow the
procedures described in Case 2 below.

▶ Case 1 – Install flat washers at center support bearing.
Install washers at the propeller shaft center support bearing when the largest angle change needed is
to adjust Θ2 in the negative direction.
NOTICE
Use a screw-jack to carefully support the propeller shaft during this procedure. Do
not allow the propeller shaft to fall onto the screw jack. Any damage to the propeller
shaft may cause an imbalance.
