Procedures

Radial Run-Out at Flange/Driveshaft, Measuring and Marking

Special tools, testers and auxiliary items required

• Dial Gauge Holder (VW 387)

• Dial Gauge

• Bolt M10x30

• Always measure radial run-out if flange has been removed. Remove old paint marking and make new marking.

• If a new driveshaft is to be installed and the factory colored mark on the rear final drive flange is no longer visible, determine the position of the maximum run-out (corresponds to the maximum distance from the rotational axis) and mark it with a colored dot - arrow B -.





• This colored dot - arrow B - is opposite the colored dot on the driveshaft - arrow A -.

• Radial run-out can be measured with rear final drive installed.

- Unbolt driveshaft from rear final drive. Refer to => [ Drive Shaft, Removing from Rear Final Drive and Installing ] Drive Shaft, Removing from Rear Final Drive and Installing.

- Attach the measuring tools to the rear final drive with the bolt - A - (M10 x 30).





- Position the dial gauge on the ground diameter - arrow - in the driveshaft flange and set to "0" with 1 mm of pre-load.

- Rotate both rear wheels simultaneously in one direction and thereby turn flange through one complete rotation.

- Make a paint marking at the point of greatest radial run-out on the outside of the flange (greatest distance from axis of rotation).

- Then remove the previous marking from the flange.
