F80 M3 Diff Output Seal

As well as the common Diff Input Seal Leak on the F80 M3, we find some diff's are leaking from one or both of the Output Seals.

Using Genuine BMW Parts and Genuine Factory Tools we can successfully remove the new style of Driveshaft (splined both ends) and replace the Diff Output Oil Seal with the assembly ring.
Then clean up the old oil leak and replace the Diff Fluid with the correct BMW MSP/A Fluid.
