How do I diagneese a bad wheel bearing on Mercedes A-Class W177?
Jack the car, grip the tyre at 12 and 6 o’clock and rock it. Excessive play indicates a worn bearing. Drive at 60–80 km/h on a quiet road — humming that changes pitch when you swerve confirms a bearing fault.
Should wheel bearings be replaced in pairs?
Not necessarily for hub-unit type bearings. Replace only the failed side. However, if the opposite bearing is close to the same mileage, replacing both saves labour costs.
