For Toyota Avensis T27 1.6 D-4D Genuine SKF Rear Wheel Bearing Kit. We apologise in advance for any inconvenience caused. With integrated ABS sensor. A Wheel Bearing is exactly what it sounds like, it’s a bearing for your wheel! On your car, it is located at the hub and is there to support the wheel and allow it to spin freely. The worst two enemies of a wheel bearing are heat and water. Heat caused by lack of lubrication can destroy a wheel bearing, and water that penetrates the sealed bearing will destroy the wheel bearing as well. A damaged or broken wheel bearing gradually becomes louder with time and speed. So when it fails, it won’t just start making a loud noise. At first, it will be a very faint noise and within a month, it will become very noticeable and will be more obvious at faster speeds.
