VW Connecting Rod Bearing - Genuine VW 04E105701GLB

Product Information

An Engine Connecting Rod Bearing is a precision bearing located between the connecting rod and the crankshaft journal in an internal combustion engine. Its role is to allow smooth rotation of the crankshaft while reducing friction and wear. These bearings are typically made from layers of soft metals (like copper, lead, or aluminum alloys) that can withstand high loads while still being sacrificial (wearing out before the crankshaft does).

• Knocking or tapping noise ("rod knock") – deep metallic knocking from the engine, especially under load or acceleration.
• Low oil pressure – worn bearings create excess clearance, reducing oil pressure.
• Metal shavings in oil – bearing material may flake off and appear in the oil or on the drain plug.

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.
