I received an email from Ethan at Nutech and of course they ask me to check in the grease for the o-ring! But considering there is no grease where the o-ring is supposed to be that was futile! I do not know what they are going to do, but I asked them to send me the large o-ring that goes between the two halves! I did get the grease out of the other diff and filled it about 60% full of 50,000wt silicone oil, so we will see how that one does!
