In particular: F20-F30 (4 cylinder turbo models, X-drive 6 cylinders and automatic models, heavier models also possible on request)
If you are bothered by noises such as singing/rattling from the differential, one of the bearings is most likely worn out. This is the weak point of this kind of differentials. We can completely overhaul your differential, so new bearings, seals, cups, etc. In this way you do not have to worry about the differential breaking again, as will happen with many used or not completely overhauled ones. The differential is blasted and painted as standard so that it is delivered as shown in the example photo.
The differential is covered by a 2-year warranty after revision.
You can also contact us for the revision of other types of differentials. We have extensive experience in racing and rally sports, where we often drive with high power, so we know the weak points of a differential like no other.
The price applies with return of your own (defective) differential. For certain models we have an exchange copy available, inquire about the possibilities.
