Because of limited space, BMW uses very small front differentials, no matter of the engine power. They are all the same. Bearing size is insufficient to handle the torque, so they break down frequently. This manifests as a whining noise from the differential, especially when you are accelerating or engine breaking.
From our experience, in 95% cases, only 2 front (pinion) bearings need to be replaced, while side bearings are in good condition. That is why we formed thisPinion bearing reparation setto save you some money.
