Audi Q7 and Porsche Cayenne Front Driveshaft 938-300

This is the front propeller shaft for the shared VW, Audi and Porsche SUV platform. It carries power from the transfer case to the front differential and replaces VW/Audi 7L0521101 (A, C, D and H versions), Porsche 95542102000 through 95542102004, Dorman 938-300 and 65-7011.

Listed fitment, AWD: 2007-2009 Audi Q7 3.6L and 4.2L; 2004-2006 Porsche Cayenne 3.2L, 2003-2006 Cayenne 4.5L, 2008-2010 Cayenne 3.6L and 4.8L; 2004-2007 VW Touareg 3.2L and 4.2L and 2007 Touareg 3.6L. Match the part number on your vehicle before ordering, since other engine and model-year versions use different shafts.

The joint boots on this front shaft sit close to the exhaust. When they crack, the grease cooks out and the joints start to knock. Common complaints are a clunk on take-off or when shifting from reverse to drive, a vibration at highway speed, and grease sprayed on the underside of the engine. The shaft is balanced as a unit, so replacing it complete is simpler than rebuilding joints.

Bench notes: remove the belly pan, mark the flanges, and support the shaft while unbolting each end. Clean the flange faces and use new bolts. If the rear shaft on a Touareg or Cayenne is also worn, the 936-301 rear shaft is listed separately.
