Alpina B5, D5 B7, BMW 7 series G12 LCI, Rolls Royce Phantom RR11 RR12 rear axle differential overhaul.
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 reconditioned ones. The differential comes standard blasted and painted so it comes as shown in the sample photo.
Installation of a locking differential is also possible.
There is a 2-year warranty on the differential 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.
