Ball Joint with lock nut suitable for Mercedes-Benz. Vehicle Repairs. We've Got What It Takes. The greatest challenge for modern, technologically complex vehicles is the balance between performance, economy, and environmental compatibility. However, many of the roads they drive on are far from perfect. As a result, the chassis and the steering are often subjected to extreme loads, which accordingly increases the quality demands placed on wear parts. Steering parts in particular are subject to special care in design, manufacturing, and assembly. In order to maintain stable road holding, even in hazardous situations, all installed steering parts must meet the high requirements of precise and high-quality production. With a large selection of safety-relevant steering components in OE matching quality, including ball joints, febi makes a contribution to road safety. Ball joints from febi are intensively tested. Our quality management tests the ball joints on offer for various requirements and loads, e.g. accuracy of fit, dimensional accuracy, material quality, and tensile strength. In the area of steering technology, febi is one of the leading suppliers in the Independent Aftermarket. The range exclusively includes ball joints that guarantee 100% driving stability. In everyday workshop life, it is not uncommon for a worn part to have to be replaced as well as any fixings. However, these additional parts - usually bolts or nuts - are often not included with the individually available replacement part. With the ProKits, febi provides a remedy and offers ball joints with all attachments required for repair at fair value (e.g. bolts, washers, and lock nuts).
