Propshaft Angle Correction Tool Help

Vibrate 5.1 has a very useful propshaft angle correction tool that graphically shows the technician how to use a shim or a cam bolt to correct a propshaft angle related vibration. Cam bolt usage to correct pinion gear angle issues on four link rear suspensions is also supported. This is the first product to ever include such a feature

This tool takes a very complex series of trigonometric calculations and makes is so easy that anyone could use it. For example: A rear wheel drive one-piece propshaft system has 8 different possible configurations and 32 possible corrections. A four wheel drive system has 32 different possible configurations and 128 possible corrections. Use the Propshaft Angle Correction Tool to assist you in deciding which corrections to make.

This feature supports the following vehicle configurations:

Two-wheel drive and Four-wheel drive vehicles.
Vehicles with one, two, or three piece rear propshafts.

To use this tool on a two-wheel drive vehicle, a technician enters 7 measurements:

1. The angle of the pinion gear. Click here to see the angle measurement tool.

2. The angle of the propshaft.

3. The angle of the transmission or transfer case output shaft.

4. The distance between the rear U-Joint bearing cap and the centerline of the rear axle shaft (Center of the wheel).
5. The distance between the centerlines of the propshaft U-Joint bearing caps.

6. The distance between the centerline of the transmission mount and centerline of the propshaft front U-Joint bearing caps.

7. The distance between the centerline of the front motor mount and centerline of the propshaft front U-Joint bearing caps.

Vibrate 5.1 calculates the front and rear U-Joint working angles and recommends the location of shim or cam bolt to use to correct unequal working angles. Depending upon the powertrain configuration and number of propshafts, the technician is given several options to correct the working angle problems.

Negative Working Angles

Occasionally the propshaft angle correction tool will calculate and show a new working angle that has a negative sign in front of it, or in other words, a negative working angle. This indicates that one or more of the components associated with that angle has changed its angle from Up to Down, or Down to Up in the process of correcting the angle.

Refer to the figure below for an explanation of up and down angles.
