WARNING: This page is about a different car, the 2004 Volkswagen R32. However, it is still accessible from the selected car via links, so may be relevant.
Drive pinion housing with shaft bevel gear and S 3 installed
Head bevel gear / input shaft installed: S 1 is on the cover side, S 2 installed in rear axle housing.
- Assemble measuring tools.
- Dimension "a" = 43.5 mm
- Screw in measuring lever VW 388 so that dial gauge extension stands at right angle to measuring surface
- Twist head bevel gear/input shaft up to stop. Set dial gauge to zero, turn back head bevel gear/input shaft and read backlash. Note value.
- Loosen clamping screw of roll pin and repeat three more times after turning head bevel gear/input shaft an additional 90 °. Add four measured values and calculate mean backlash.
