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.

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.
