2. Procedure: note the EXACT location of the factory seal and replicate that.
In general, it is about 1-2mm from the INNER side of the bevel edge.
Install too deep: you will get a leak.
This is bc the factory seal is used to the corresponding "grooves": look carefully on the axle, you will see shiny grooves created by the factory seal.
PS: It looks like it is coming from the engine side. However, it can come from the FRONT DIFF side too.

You are correct it’s coming from the diff side as all the oil leaked is not engine oil.
Both side shafts are new twice and the seals are from the dealership Tha only thing I think of is it may be that the oil pan somehow expanded? The other aides from the passenger side not leaking or the other side of the diff only the middle. If the price was not a little high I would changed the oil pan too.
