HELP Rear axle leaking

[Lachie]

I have a TEA20 ive just rebuilt it and filled the trans and diff with oil only to watch it drip out again
Its leaking on the right hand side where the 3pt lift arm joins the diff.Ive undone the one and only nut holding the pin the the housing but i cant pull it off it wiggles but wont come off do i need to split the diff to fix this leak???
Any help would be greatly appreciated as oil isnt cheap
Regards

How much oil did you put in this system. It only takes 7 1/2 to 8 gal when it has been drained all the way.

You have to take that rear axle trumpet housing off the differential housing. There is a nut on the inside of the axle housing that holds the lift arm pin in place. Must be leaking around there.

Thank you for your replies
I put 20L in all up it recommends 22L The trumpet your referring to that's the trumpet looking piece with like a dozen or more bolts right round can i reuse the gasket and could you give me a run down on pulling it all apart because i don't want to loose any shims etc
thanks again
