Differential Pinion seals weeping?

OK Thanks for the info - will bear that in mind.
I got a response from the (Queensland Australia) dealer this morning - see below for what its worth
Might be something to check in any case -

@NQ94 contributed over in the diff breathers thread here that the diff input seal may be a cassette type. You can see in the example seal he posted there are several (5) seal lips that need to be lubricated during operation. Someone else speculated in that thread that the housing breather might maintain a low pressure to (keep water out plus) ensure some oil/mist is pushed past the seal to ensure adequate lubrication. That accords with what your agent is saying. The weeping would appear excessive if the breather is blocked or out of spec. It's a cheap low tech ball and spring device.
The problem is, how much weeping is normal for this seal type and are we accustomed to assessing leakage rates for conventional single or double lip pinion seals that run on the yoke sleeve and tend to only weep when they're starting to fail?
I'd love to hear from a Carraro rep on this, or even an experienced Iveco guy who doesn't have a brand to defend.

Edit: tipos typus typos 🙄
