Audi Engine Crankshaft Main Bearing - Genuine VW Audi 06H105591JWEI

Product Information

An engine crankshaft main bearing is a crucial component that supports the crankshaft in the engine block and allows it to rotate smoothly. These bearings are typically metal shells lined with a soft, durable material (like babbitt or a copper-lead alloy) and sit between the crankshaft journals and the engine block, and helps maintain proper oil clearance for lubrication.

• Knocking or Thumping Noise from Engine (Rod Knock or Main Knock): Often heard at low RPM or under load; a classic “engine knock” indicates excessive bearing clearance.
• Low Oil Pressure: Worn bearings increase oil clearance, causing a drop in oil pressure readings.
• Metal Shavings in Oil: Bearing material can wear off and contaminate engine oil.

About Genuine VW Audi

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.

You may not realize this, but the parts that make up your VAG are not necessarily manufactured by VAG. No cause for concern, as VAG designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VAG 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 VAG parts box and find an OEM branded part inside, simply with the addition of a VAG 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.
