Disco 1 Rear diff leaking

Folks
I went to Yarwell yesterday and did some wading (above the axle, I have extended breathers) and when I got home I noticed a substantial amount of diff oil dripping on the floor below the axle. When I looked further it was all over axle case and the rear of the chassis to the point of dripping and even on the crossmember in front of the fuel tank. Oddly did not seem to be looking like it was dripping from pinion seal.

When I drained the diff it was milky as it must have had lots of water ingress but my question is would the ingress have forced the oil out over everything. No leaks were noticeable before this.

Thanks for any suggestions.

Oil floats on water so if you filled the axle up with water the oil would overflow.

Btw the Nottingham derby border is in the posh place called Toton Beeston is well into Nottingham near a dump called Lenton.
Breaston is a real posh place and should not be confused with Beeston.

I am looking down on you all from my hill......

Was born and raised in Breaston, now living in Beeston..
