Ford Fusion: Driveshaft / Driveshaft Angle Measurement. General Procedures

Check

NOTE
- Special Tool(s): Anglemaster II Driveline Inclinometer/Protractor 164-R2402. Perform the following preliminary setup steps:
1. Inspect the U-joints for proper operation.
1. Park the vehicle on a level surface, such as a drive-on lift, or back it onto a front alignment rack.
1. Make sure the ride height at the curb position is within specification with the vehicle unloaded and all tires inflated to normal operating pressure.
1. Calibrate the Anglemaster II Driveline Inclinometer/Protractor by placing it on a clean, level section of the frame rail and pressing the ALT-ZERO button.

Vehicles with U-joints with flanged yokes, roll pins or slip flanges.

NOTE
If equipped, remove the retainer ring to access the base of the U-joint cup. Make sure the Anglemaster II Transmission Inclinometer/Protractor is seated against the U-joint cup.
Rotate the driveshaft until the U-joint flange cup is parallel to the floor. This will make taking measurements easier.
Special Service Tool(s): Anglemaster II Transmission Inclinometer/Protractor 164-R2402. Check and record the flange angle as Angle A.
2
Special Service Tool(s): Anglemaster II Transmission Inclinometer/Protractor 164-R2402. Measure the angle of the connecting component. Record the component angle measurement as Angle B.

NOTE
Repeat this step for each center support bearing on the propeller shaft.
It is not necessary to remove the universal joint snap ring, if equipped, for these measurements.
Special Service Tool(s): Anglemaster II Inclinometer/Protractor 164-R2402. Measure the inclination of the components in front of and behind the propeller shaft center support bearing at the area indicated. Record the front component as Angle A and the rear component as Angle B.

1
NOTE
When 2 connected components are inclined in the same direction, subtract the smaller number from the larger number to find the universal joint working angle. When 2 connected components are inclined in opposite directions, add the measurements to find the universal joint working angle.
Calculate the difference in component angles to determine the universal joint working angle.
2
NOTE
- The universal joint working angle is the angle formed by the two yokes connected by the cross and bearing kit. Ideally, the working angles at each propeller shaft joint should:
1. be equal to or within one degree of each other.
1. have a maximum working angle of 3 degrees.
1. have at least one-half degree of continuous working angle.
3
If the angle does not meet specification, repair or adjust to obtain the correct angle. Inspect the engine mounts, transmission mounts, center support bearing cushion, rear suspension, rear axle, rear axle mount or frame for wear or damage.
