I just assembled my M05 ball diff, with ceramic balls and the 416 nut, using AW grease inside as suggested by Cal, but I don't have any specific thrust bearing grease.
Is it really essential that I buy some tomorrow or is it ok to use AW grease for this?
And why is the 416 screw not being used as well as the nut? It is only 3mm shorter and seems long enough to use?
Thanks
