Hello!

1.
I dont know how this part (picture) is called. How can I disassamble that part to change the sealings and the bearing?

2.
I tried 3 times to mount the spiral with the ***** (I also dont know the name), but it wont work. What is the right way to mount the *****. How I have to start?

3. How much gear fluid do I have to do in the differential? (8.2" 10bolt)

Thank you very much for your answers
