As a proud BMW E91 owner, you value its driving comfort and reliability. But what happens when you hear a grinding noise from the rear wheel, especially when cornering? There’s a good chance the rear wheel bearing on your BMW E91 is defective. This article provides a comprehensive overview of this crucial component, explains the symptoms of a faulty wheel bearing, and guides you through DIY repair steps.
The Importance of Wheel Bearings for Your BMW E91
The wheel bearing, an unassuming component inside the wheel hub, plays a vital role in the driving safety and comfort of your BMW E91. It allows the wheel to rotate smoothly while absorbing shocks and vibrations encountered during driving.
Imagine driving your E91 on a bumpy country road. Without functioning wheel bearings, the wheels wouldn’t turn properly, driving comfort would be compromised, and steering would become inaccurate.

Symptoms of a Faulty Wheel Bearing on a BMW E91
A defective wheel bearing usually announces itself through various symptoms. The most common signs include:

- Unusual vibrations in the steering wheel: A faulty wheel bearing can cause vibrations that can be felt in the steering wheel.
