If you are experiencing side noises such as singing/rattling of the differential then most likely one of the bearings is worn out. This is the weak point of this type of differential. We can completely overhaul your differential, so new bearings, retaining rings, cups, etc. This way you don't have to worry about the differential breaking down again, as will happen with many used or not fully rebuilt ones. The differential comes standard blasted and painted so it comes as shown in the sample photo.
From the factory, the 190AL has an internal lubrication problem which can lead to extreme bearing wear and therefore differential failure. It is not entirely unwise to have your differential rebuilt before it is due or develops problems. During revision we solve this problem. For the 330E we may have a complete solution to make the driveline stronger: https://hardemanmotorsport.nl/bmw-3-serieg20-g26-g29-z4-en-g42-2-serie/#190AL_Aluminium_achter_differentieel
The differential is guaranteed for 2 years after revision.
You can also contact us for revision of other types of differentials. We have extensive experience in the racing and rally sport where mostly high power is driven so we know the weak points of a differential like no other.
The price includes the return of your own (defective) differential. For certain models we have a replacement available, please inquire about the possibilities.
