hi members. i'm new here. i have  2005 Tucson 2.0L 5-speed diesel engine.

i need the part number of an oil seal (See the picture). i don't know it's number, but it is located between the suspension arms and the gear (my mechanic said something about "transfer case")/
i have it in my hands, but the only numberi see is "d(htc) 54 78 8 pos 7"
the outer dimater is 7.2cm
the inner is 5.5cm,
the most unique thing about it is that it has marks (on the inner edge) like teeth left and right.

do you have any idea which seal is this ? and offcouse the part number ?
thanks in advnaced

look at the red color lines i drew on it. in the picture i took it can't be shown, but i tried to illustrate it in drawing (Red marks), this is what so special about this seal. i need the original. not aftermarket.
