Nissan Patrol 4x4 (Africa)

Hey everyone,

Firstly, just a heads- up, I am probably the least mechanically minded person on this forum so forgive me for any stupidity!

I have an oil leak coming through a seal on the half shaft (I think it's called that!) Please could you have a look at the attached photo and exploded axle diagram and help me I.D. the parts? I have indicated with arrows what I'm looking for on the photo, and circled in red the photographed area on the axle diagram.
I'm currently working in Northern Zambia and for 3 weeks I've been tearing my hair out trying to get someone competent enough to tell me what it is! Nissan S.A. haven't been very helpful either.

The vehicle is a Nissan Patrol GR Y61.

Thanks a lot!

Hi Terry

Nissan part number N4053301j00, called "Seal -oil inner Driveshaft", price around R227.59 excl two months ago.

I have not been able to source this seal from a bearing agent.

Thanks Peter!
