My JB74 has been making a popping sound from the rear for a few weeks now. Thought I’d check underneath today and oil was peeing out of the rear, I’ve taken a video and tried to attach it to this post if anyone can advise me how to fix it! Thanks

That liquid looks a little too thin to be gear oil, I'd suggest you check the brake fluid reservoir ASAP.

I agree it looks thin for diff oil but with that much leaking there would be no brakes already

I would go for a diff that is full of water and oil, have you been wading it?

No, haven’t been off-road in it since the Big Jimmy meet, I did change the diff oil a few weeks ago and it was as clean as a whistle

Smell and feel the oil on your fingers, brake fluid is less lubricative if that is a word.
You may have leftovers from your gear oil change and can smell/feel if it is the same?
And/or smell/feel the brake fluid in the reservoir?

Check that the breather on top of the axle is free and the level is correct. It could be a blocked breather is pushing oil past the shaft seal?
