transmission seal durability R380/LT230

[Don 130]

About 18 months ago I got the seals in my transfer replaced, and the gearbox replaced with a reconditioned exchange. Now there's a leak from the weep hole between the two. It's about the size of a hand print on the shed floor overnight. The question is, how long should I reasonably expect the seals to last, and what is unacceptable. The original setup lasted for years before leaking started. I'm disappointed with what has happened.

Don the quality of many aftermarket seals is poor so possibly this is what you are experiencing,
The seals can last for hundreds of thousand kms provided the sealing surfaces are OK
I would replace with Corteco seals (check the mating surface though)

Does anybody know the part numbers for the input/output oil seals for the gear box and the transfer case for R380 series box?

Doing a change over of box and thought replacing fluid seals while at it would be prudent.
Haven't separated box and transfer case yet, so can't remove seals to get numbers off them.
Not able to nip down to local LR specialist (1650k's away), but if I can get the seal numbers, the local bearing/seals place might be able to supply.
