Sven Nielsen, Technical Director from MEYLE, says the following difficulties may arise with the Renault Megane:
Defective wheel bearings
Loud metallic rolling noises are indicators of defective wheel bearings. Increased wheel bearing tolerances can also be diagnosed by tilting the wheel while the car is not under any strain. In order to prevent more serious damage or the complete loss of the wheel bearing, the driver should seek the assistance of a workshop as soon as possible.
In the event of a defective wheel bearing, it is recommended to always also check the other axle bearings because it has to be presumed that all wheel bearings are exposed to the same stressors and are thus likely to have similar life times.
The wheel bearing we recommend here is a first generation bearing that possesses high quality seals that avoid the penetration of water or humidity. Should water enter, the bearing will fail within a short time. It is vital not to damage the seals during installation.
Please remember that on some occasions special tools are needed for the installation. A force fitting of these bearings across the outer ring will seriously damage the bearing and will cause premature failure.
