Audi VW Drive Shaft - Genuine Audi VW 4N4521101D

Product Information

A driveshaft is a rotating metal shaft that transmits power from the transmission to the rear wheels in a vehicle, and signs of a failing driveshaft include: noticeable vibrations while driving, shuddering when accelerating, loud clicking or clunking noises, squeaking sounds, and difficulty turning, often accompanied by shaking coming from underneath the car; all of which are usually caused by worn-out U-joints or center bearing issues within the driveshaft assembly.

• Vibrations: This is the most common sign of a failing driveshaft, often felt as a shaking sensation while driving, especially at higher speeds
• Shuddering upon acceleration: When accelerating from a stop, the car may jerk or shudder due to a damaged driveshaft struggling to deliver smooth power
• Noises: Clicking, clunking, squeaking, or rattling sounds coming from the drivetrain area can indicate worn components within the driveshaft

About Genuine Audi

The original parts used by Audi to build your car are available as replacement parts under the “Genuine Audi” brand. Manufactured under the direction of Audi, expect excellent quality and a premium price since these parts are available exclusively through the Audi Dealership network.

You may not realize this, but the parts that make up your Audi are not necessarily manufactured by Audi. No cause for concern, as Audi designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Audi for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Audi parts box and find an OEM branded part inside, simply with the addition of an Audi logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
