BMW Subframe diagram for 740i, 740iL, 750iL

A Suspension Subframe Crossmember (often just called a subframe or crossmember) is a structural component of a vehicle’s chassis. It is a strong metal frame or beam that spans across the underside of the car and serves as a mounting point for key suspension parts (like control arms, stabilizer bars, and sometimes the steering rack or engine mounts).

It essentially acts as the backbone that ties suspension components together while connecting them securely to the vehicle’s body or unibody.

• Clunking or knocking noises – from loose or shifting suspension parts mounted to a weakened frame.
• Poor wheel alignment / uneven tire wear – caused by improper suspension geometry.
• Vehicle pulling to one side – suspension no longer aligned correctly.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

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