AFTERMARKET FAST FAHREN provides some technical insight on wheel bearing kits as part of their comprehensive and diverse component portfolio. Fahren continually develops their specific ranges to reflect the ever-evolving demands of the UK aftermarket. By continuing their efforts to offer a diverse range of competitively priced, fast-moving components, Fahren presents strong opportunities within its product range. In 2017, Fahren bolstered their offering with new-to-range references added to their portfolio. For example, their established wheel bearing kit (WBK) range which currently stands at more than 120 references had more than 40 new references added at the end of 2017. UNCOMPROMISED QUALITY While offering the aftermarket with cost-effective replacement solutions, Fahren strives to stay true to their standard in uncompromised quality. As with the other components in the Fahren portfolio, WBKs are subjected to intense scrutiny in pre-tests to ensure that they meet the highest recognised quality standards. Fahren takes extensive measures to ensure that their WBKs adhere to strict quality guidelines. These include ensuring that the exacting dimensions of the inner and outer rings, axial clearance, material hardness, rust, end-runout and magnetic field checks all match OE specifications. SIGNS FOR REPLACEMENT There are several symptoms that indicate a failing WBK. The most common symptoms include: • Grinding or knocking sounds (at low speed) • Whining sounds (at high speed) • Uneven tyre wear • Shuddering or vibrations at constant speed These symptoms are likely to surface as a result of poor installation, damage from an accident or a damaged wheel bearing seal. A damaged seal allows moisture and debris to enter the bearing, leading to failure over time. 4 WHEEL BEARING KITS REPLACEMENT TIPS Fahren recommends that the following guidelines are observed to help ensure proper replacement; • Work with clean tools in clean surroundings • Always choose the correct grease • Follow the correct installation procedure as advised by the vehicle manufacturers. • Be sure to check the condition of the housing and axle when changing wheel bearings. Even the smallest wear will lead to misalignment, resulting in premature failure. • Be mindful to check the contact surface for the seal lip. The smallest mark or rust can damage the seal lip, allowing water penetration and eventual corrosion. • Hub unit clearances are already set at the factory with the correct preload – never attempt to set clearances on hub units. However, the installer can tighten the nut to the correct preload as advised by the workshop manual. Most importantly, never attempt to take a hub unit apart before mounting. This will damage the raceways and seals, destroying the bearings which will lead to failure.
