Transfer case chain (PL72 T) – 1,25 inch – 3,175 cm.

Jerking, shuddering, or a rhythmic clicking sound under load often indicates that your transfer case chain has stretched. When the chain loses its tension, it skips over the sprocket teeth, disrupting power flow to the front wheels. Replacing the chain with a new PL72 T unit usually resolves these symptoms.

Yes, the PL72 T transfer case is commonly found in Audi Q7, VW Touareg, and Porsche Cayenne models. This specific chain is 1.25 inches (3.175 cm) wide, which is the standard specification for these heavy-duty 4×4 systems. We recommend verifying the ID tag on your transfer case before ordering.

The most common signs include vibrations felt through the floorboard, a “clunking” noise when engaging 4WD, or the 4×4 system failing to deliver power to the front axle properly. If you notice metal shavings in your transfer case fluid, it is a clear sign of internal wear.

Replacing the chain requires opening the transfer case housing. While it is a more affordable alternative to replacing the entire unit, it requires mechanical expertise and specific tools. We recommend a professional installation to ensure the internal seals and bearings are properly seated.
