One-Piece Propeller Shaft

Fig. 10:

To accurately check driveline alignment, raise and support the vehicle at the axles as level as possible. Allow the wheels and propeller shaft to turn. Remove any external bearing snap rings (if equipped) from universal joint so that the inclinometer base sits flat.
1. Rotate the shaft until transmission/transfer case output yoke bearing cap is facing downward.
Always make measurements from front to rear.

2. Place Inclinometer on yoke bearing cap (A) parallel to the shaft. Center bubble in sight glass and record measurement.
This measurement will give you the transmission or Output Yoke Angle (A).

Fig. 8:

3. Rotate propeller shaft 90 degrees and place Inclinometer on yoke bearing cap parallel to the shaft. Center bubble in sight glass and record measurement. This measurement can also be taken at the rear end of the shaft.
This measurement will give you the propeller shaft Angle (C).
4. Subtract smaller figure from larger (C minus A) to obtain transmission output operating angle.

Fig. 9:

5. Rotate propeller shaft 90 degrees and place Inclinometer on pinion yoke bearing cap parallel to the shaft. Center bubble in sight glass and record measurement.
This measurement will give you the pinion shaft or input yoke angle (B).
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 joint operating angles (within 1°).
- Operating angles less than 3°.
- At least 1/2 of one degree continuous operating (propeller shaft) angle.
