Mercedes Steering Knuckle Right (E350 E550) - Genuine Mercedes 2123321000

Product Information

A steering knuckle connects the wheel hub, suspension, and steering components, enabling the wheel to pivot for steering while supporting vertical load from the vehicle’s weight. The knuckle provides mounting points for the control arms, tie rods, strut, or spindle, depending on the suspension design, and houses the wheel bearing, allowing the wheel to rotate freely.

• Steering Misalignment: If the steering knuckle is bent or damaged, it can cause alignment issues, making the vehicle pull to one side and causing uneven tire wear
• Excessive Vibration: A damaged knuckle can disrupt the wheel's connection to the suspension and steering components, resulting in noticeable vibration, especially at higher speeds
• Poor Handling: When the knuckle is compromised, it may lead to poor handling, with the vehicle becoming less responsive to steering inputs or feeling unstable

About Genuine Mercedes

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