Propeller Shaft Angle
WARNING: This page is about a different car, the 2004 Dodge Dakota and 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
- Remove any external bearing snap rings, if equipped, from universal joint so protractor base sits flat.
- Rotate the shaft until transmission/transfer case output yoke bearing is facing downward.NOTE: Always make measurements from front to rear and from the same side of the vehicle.
- Place Inclinometer 7663 (J-23498A) on yoke bearing (A) parallel to the shaft (Fig 1
). Center bubble in sight glass and record measurement.
This measurement will give you the transmission or Output Yoke Angle (A).
- Rotate propeller shaft 90 degrees and place Inclinometer on yoke bearing parallel to the shaft (Fig 2
). 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).
- Subtract smaller figure from larger (C minus A) to obtain Transmission Output Operating Angle.
- Rotate propeller shaft 90 degrees and place Inclinometer on pinion yoke bearing parallel to the shaft (Figure
). Center bubble in sight glass and record measurement.
This measurement will give you the pinion shaft or Input Yoke Angle (B).
- Subtract smaller figure from larger (C minus B) to obtain axle Input Operating Angle.
Refer to rules given below and the example in (Fig 3 ) 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.
