Hello!

Could some one please advice some tips why my differential is leaking. I have buyed new Reconditioned diff and installed it correctly to lr2. There is no leaks on any gaskets, the leak is under of differential and there was tiny 1-2mm hole bottom of diff and lr seller told me that they have never seen suchlike of drill / hole under differential, but i have used some chemical metallic padding to fill the 1-2 mm hole. The leak is comming under 4k007, i dont want to drop the differential again to search the leak, but this is realy wierd? here is photo of the hole which i have padded, is it possible that its crackked somehow or what the hell?
The oil is differential oil, not haldex oil because the oil is sticky, and haldex isnt stickky

The isnt comming anymore on the hole, because i have filled it totaly whit padding, but it comes still somewere under the 4k007, and there should not be anything gaskets....

kindly regards jonny kurki from finland
