I have no idea what a seadiff is but I assume you were referring to the pinion seal? I wonder if your axle vent tube is plugged?

I have seen where a pinion seal is leaking badly but rather than replace the seal someone has drained the oil and actually put grease into the rear end just to sell the vehicle. The oil should be a synthetic gear oil at least 75w90 and 75w110 if you are towing hard.

I get that part but, they don't get hot for no reason. Their was a cause that allowed them to get hot.
What is going to prevent them from getting hot again if their was no cause determined?
