technical info needed on diff seals please.

[G60-R]

as my last thread said. oil everywhere!!!!! after investigation i discovered it was leeking from the prop shaft end. i ordered a seal from milners. after it arrived i pulled the lot apart to see that the seal that milners sent me didn't exist behind my companion flange. there just seemed to be a seal set in the diff casing. the seal i was sent did fit well on the companion flange. not sure what to do i ended putting the new seal in what looked like the right place, reasembling the bits and took it for a drive. still leeking

is this the wrong seal for my truck?? do i need the one set into the diff casing? please help. need truck for work!! have put new breather on.

see pics. No. 1 = existing oil seal type thing
No.2 = oil seal sent by milners
No.3 = oil seal on flange

the seal is inserted into the diff! - it doesnt just sit loosely on the flange! (well thats my understanding of your description ?)
i have used screw driver to prise out the old ones when replacing them
your existing seal is same as the milners by look of things
