Power steering racks (rack and pinion) are usually a lifetime component for most cars. However, there are certain scenarios in which a power steering rack can fail and will need to be replaced. We often find that poor maintenance of the system (leaks, old fluid, damaged hoses) can cause premature failure. Part failures within the rack itself are also common. Seals can fail causing leaks and poor system pressure. We also find that worn inner tie rod boots that are damaged can allow for water, dirt, and other contaminants to get inside the rack causing havoc with the power steering system as a whole. If you rack is leaking or making grinding sounds, it will need to be replaced.

• Leaks at sealing points
• Tight steering feel
• Grinding noises
• Numb spot in steering
• Car wandering

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.
