2463340006 BEMWQ Wheel Hub Bearing for Mercedes Benz X156 W176 W246 C117 M270

The 2463340006 Wheel Hub Bearing is a precision-engineered, complete hub and bearing assembly specifically designed for the rear axle of several compact Mercedes-Benz models. This OE-grade component is the direct replacement for original part number 2463340006 and serves as a critical interface between the vehicle's wheel and suspension system. Its primary functions are to support the vehicle's weight, provide a stable and frictionless axis for wheel rotation, and withstand the complex combination of axial and radial forces generated during steering, cornering, and acceleration . As a complete "hub unit," it integrates the wheel flange, dual bearings, and precision seals into a single, pre-assembled package. This advanced design ensures precise wheel alignment, minimizes rotational play, and delivers the signature smooth, quiet, and stable ride quality expected of the Mercedes-Benz brand .

The 2463340006 hub bearing is specifically compatible with Mercedes-Benz vehicles built on the company's versatile front-wheel-drive (MFA) platform, which includes the W176 (A-Class), W246 (B-Class), C117 (CLA-Class), and X156 (GLA-Class) , all powered by the M270 engine .

• OEM Direct Fitment: Engineered to match the exact specifications of original Mercedes-Benz part number 2463340006, ensuring a seamless and precise fit for your vehicle without modifications .

• Complete Pre-Assembled Hub Unit: Unlike older, multi-piece bearing designs that require complex assembly and adjustment, this is a modern, pre-assembled unit. It arrives ready for a simple bolt-on installation, which eliminates the need for time-consuming bearing packing, seal fitting, and clearance adjustments .

• Rear Axle Placement: A robust component specifically engineered to manage the unique load and dynamic forces applied to the rear wheels of the vehicle .

• Precision-Engineered Rolling Elements: Manufactured with rigorously controlled processes to ensure exact matching of the bearing raceways and rolling elements. This precision is key to delivering superior performance, long service life, and minimizing noise and vibration .

• Robust and Durable Construction: Built with high-grade materials, including a durable flange and housing. While specifications may vary slightly by manufacturer, the unit is designed to meet the high durability standards expected by Mercedes-Benz .

• Integrated ABS Functionality: This hub bearing is available in configurations that fully support the vehicle's Anti-lock Braking System (ABS). It functions as a magnetic encoder, providing accurate wheel speed signals to the ABS and Electronic Stability Program (ESP) modules for crucial safety systems .

• Premium-Grade Sealing: Features high-quality, integrated seals that protect the precision internal bearings from water, road salt, dust, and other contaminants. This sealing is vital for maintaining lubrication and preventing premature wear .

• Corrosion-Resistant Finish: The hub unit's exterior surfaces are treated with a protective coating to resist corrosion, ensuring ease of future disassembly and extending its operational life in harsh road conditions.

• Eliminates Annoying Roaring and Grinding Noises: The most common sign of a failing wheel bearing is a loud, cyclical droning, roaring, or grinding noise that increases with vehicle speed. Replacing a worn bearing with this OE-quality unit instantly eliminates these disruptive sounds, restoring the whisper-quiet cabin environment of your Mercedes-Benz .

• Restores Proper Wheel Stability and Steering Precision: A worn hub bearing allows for excessive play in the wheel, which can cause a vague, wandering steering feel and poor handling. Replacing it restores the precise wheel control and confident, planted feel that allows the vehicle to track straight and true.

• Essential Safety for ABS and ESP Systems: A damaged or corroded wheel bearing can cause erratic signals to be sent to the ABS control module, potentially triggering a dashboard warning light and disabling your anti-lock brakes and stability control systems. This OE-spec hub bearing is designed to provide a clean, consistent signal, ensuring your Mercedes-Benz's critical safety systems are always ready to perform .

• Specifically Designed for Your MFA Mercedes-Benz: This hub bearing is not a generic, "one-size-fits-all" part. It is specifically engineered for the precise weight, power, and suspension geometry of the compact Mercedes-Benz models (W176, W246, C117, X156) with the M270 engine family, guaranteeing a perfect fit and optimal performance .

• Enhances Fuel Economy: A worn bearing with damaged rolling elements creates significant friction. By replacing it with a smooth, low-friction hub assembly, you help reduce parasitic drag, which can contribute to a minor but measurable improvement in your vehicle's fuel economy.

• Simplified, Press-Free Installation: Because this is a complete hub assembly, installation is significantly more straightforward than replacing a traditional pressed-in bearing. It bolts directly to the steering knuckle, requiring no specialized hydraulic press. This saves valuable diagnostic and labor time for professional mechanics and makes the replacement a viable project for experienced DIYers .

• Premium OE-Quality from Trusted Brands: This critical safety component is available from world-class manufacturers, including SKF and MOOG, who are trusted OE suppliers and leaders in bearing technology . For example, the SKF VKBA6786 is a direct cross-reference that provides the same level of quality, performance, and durability as a bearing purchased directly from a Mercedes-Benz dealership but at a more competitive price point .

• Long Service Life and Reliability: Engineered with advanced rolling element technology, high-quality steel, and superior sealing, this hub bearing is built to provide years of trouble-free service, easily matching or exceeding the durability of the original factory-installed unit .

• Carries Strong Warranty Coverage: When purchased from a reputable brand, this hub bearing is backed by a substantial warranty, providing peace of mind. For example, the SKF VKBA6786 comes with an industry-leading 4-year warranty, a testament to its exceptional build quality and the manufacturer's confidence in its product . Many other quality options include a 1-year warranty as well .

• One Part Number for Multiple Models: The high degree of parts sharing across the Mercedes-Benz MFA platform means that this single part number (2463340006) is the correct replacement for a wide range of popular models, including the W246 B-Class, W176 A-Class, C117 CLA-Class, and X156 GLA-Class. This simplifies parts ordering and management .
