Tribute 4WD L4-2.3L Hybrid (2008)
5. Calculate the difference in the slope of the components to determine the U-joint operating angle.
-
When 2 connected components slope in the same direction, subtract the smaller number from the largest to find the U-joint operating angle.
When 2 connected components slope in the opposite direction, add the measurements to find the U-joint operating angle.
-
The U-joint operating angle is the angle formed by 2 yokes connected by a cross and bearing kit. Ideally, the operating angles on each end of
the driveshaft must:
-
be equal or within 1 degree of each other.
-
have a 3 degree maximum operating angle.
-
have at least 1/2 of 1 degree continuous operating angle.
6. If the driveline angle is not the cause of the concern, carry out the NVH test to determine whether the concern is caused by a condition in the rear
axle. See See: Steering and Suspension/Suspension/Testing and Inspection/Symptom Related Diagnostic Procedures/Noise, Vibration And
Harshness (NVH).
7. If the angle is not within specifications, repair or adjust to obtain the correct angle. Inspect the engine mounts, transmission mounts, center support
bearing mounting, rear suspension, rear axle, rear axle mounting or the frame for wear or damage.
Driveshaft Indexing
DRIVESHAFT INDEXING
NOTE: If indexing the driveshaft does not eliminate the vibration, balance the driveshaft. See See: Driveshaft Runout And Balance.
1. With the vehicle in NEUTRAL, position it on a hoist. See See: Maintenance/Vehicle Lifting/Service and Repair/Lifting.
