Problems associated with the supply of the synchronous shaft

Hello I ask for help from the axle special lists! That with the axle balls always a slight fat release seems to be normal. But with my G it is recently a grey fat film mixed with oil. The diff oil which was recently exchanged was also gray. So probably the cuffs and the sealing rings are broken, but strangely simultaneously on both sides. I ordered now new seals and bearings and disassembled the first side. At the cuff which still in Ordn ung the tensioner has opened and the cuff was loose at the larger diameter. Unfortunately, the DC joint is also to be replaced. A drive shaft for the G is quickly found, but not suitable for my G500 Bj.10 388Ps at least if the information of the providers is correct. I doubt however the accuracy of the according to dimension should fit e.g. these except the teeth number for ABS: https://www.autodoc.de/…/1386668?… Does someone know about the different equals I’m a little bit in need of time as I’m about to leave Tunisia. I’ll at least thank you for reading. Sincerely, Charlie
