Drive/Propeller Shaft: Testing and Inspection

Radial Run-Out on Flange/Driveshaft, Measuring and Identifying

Special tools, testers and auxiliary items required

• Universal Dial Gauge (VW 387)

• Dial Gauge

• Bolt M10•30

• Radial run-out must always be measured if the flange/driveshaft at rear final drive was removed. For this, make new color marking and remove old color marking.

• If a new driveshaft is installed and the color marking on the drive flange of the rear final drive is no longer visible, location of largest radial run-out (corresponding to greatest distance from turning axis) must be determined and marked with a color marking - arrow B -.





• This color marking - arrow B - is set opposite the color marking on the driveshaft - arrow A -.

• The radial run-out can be measured with the rear final drive installed.

- Remove driveshaft from rear final drive. Refer to => [ Driveshaft from Rear Final Drive ] Driveshaft From Rear Final Drive.

- Secure measuring tools with bolt - A - (M10x30) to rear final drive.





- Set dial indicator onto ground diameter in inside of driveshaft flange - arrow - and set to 0 with 1 mm preload.

- Turn both rear wheels in one direction at the same time so that the flange makes one complete turn.

- Mark the largest radial run-out on the outside of the flange with color dot (corresponding to the largest distance from the turning axle).

- Then remove the previous marking from the flange.

- Attach the driveshaft => [ Attach the Driveshaft to the
