Tribute 4WD L4-2.5L Hybrid (2009)
Drive/Propeller Shaft: Procedures
Driveline Angle Measurement
DRIVELINE ANGLE MEASUREMENT
NOTE:An incorrect driveline angle can cause a vibration or shudder.
NOTE:Prior to checking driveline angularity, inspect the U-joints for correct operation.
NOTE:An incorrect driveline angle can cause a vibration or shudder. See - See: Steering and Suspension/Suspension/Testing and Inspection/Symptom
Related Diagnostic Procedures/Symptom Troubleshooting Chart - Noise, Vibration And Harshness (NVH).
NOTE:Driveline angularity is the angular relationship between the engine crankshaft, the driveshaft and the rear axle pinion. Factors determining
driveline angularity include ride height, rear spring and engine mounts.
1. Carry out the following preliminary setup procedures.
a. Inspect the U-joints for correct operation.
b. Park the vehicle on a level surface such as a drive-on hoist or back onto a front end alignment rack.
c. Verify the curb position ride height is within specifications with the vehicle unloaded, and all of the tires are inflated to their normal operating
pressures.
d. Rotate the transmission output yoke until vertical. This will simplify taking measurements.
e. Calibrate the Anglemaster II Driveline Inclinometer/Protractor by placing the tool on a clean, flat, level section of the frame rail and press the
ALT-ZERO button.
2. To check the U-joint operating angle, install the Anglemaster II Driveline Inclinometer/Protractor. Check and record the flange angle as angle A.
NOTE:Remove the snap ring to allow access to the base of the U-joint cup. Make sure the Anglemaster II Driveline Inclinometer/Protractor is seated
against the U-joint cup.
NOTE:Rotate the driveshaft until the flange U-joint cup is parallel with the floor. This will simplify taking measurements.
