Standard Procedure

PROPELLER SHAFT ANGLE





NOTE: This procedure applies to the front and rear propeller shaft.

1. Raise and support vehicle at the axles as level as possible, allowing wheels and propeller shaft to turn.
2. Remove universal joint snap rings if equipped, so inclinometer base will sit flat.
3. Rotate shaft until transmission/transfer case output yoke bearing cap is facing downward.

NOTE: Always make measurements from front to rear and from the same side of the vehicle.

4. Place Inclinometer 7663 on yoke bearing cap or pinion flange ring, parallel to the shaft. Center bubble in sight glass and record measurement (A).

This measurement will give you the transmission or Output Yoke Angle (A).





5. Rotate propeller shaft 90 degrees and place Inclinometer 7663 on yoke bearing cap parallel to the shaft. Center bubble in sight glass and record measurement (C). This measurement can also be taken at the rear end of the shaft.

This measurement will give you the propeller shaft angle (C).





6. Subtract smaller figure from larger (C minus A) to obtain transmission output operating angle.
7. Rotate propeller shaft 90 degrees and place Inclinometer 7663 on pinion yoke bearing cap parallel to the shaft. Center bubble in sight glass and record measurement (B).

This measurement will give you the pinion shaft or input yoke angle (B).

8. Subtract smaller figure from larger (C minus B) to obtain axle Input Operating Angle.

PROPELLER SHAFT ANGLE RULES

- Good cancellation of U-joint operating angles is within 1 degree.
- Operating angles less than 3 degrees.
- At least 1/2 of one degree continuous operating (propeller shaft) angle.
