I can't see the seal spring in your pictures, meego. It's a while since I've done mine, but pretty sure that's ok.
That’s the front hub and I think it only has an inner seal. Thanks anyway mate.
That’s the one. Still not showing what way it goes in.
I’m convinced it’s in wrong. The open face where you can see the spring should always go on the oil side, and this one is on the outside.

I'm sure the spring side goes in first (otherway to how yours are at the moment), seem to remember it says on the seal (maybe not on all) 'this side out' or something like that.

No problem meego, I thought my rear hubs were similar to the front.

Yep, it's got darker here now (camping in Germany) and I can see the spring in the second picture. That should be the other way around.

Early versions of the hub did not have that seal, the hub was lubricated by oil migrating from axle [ my 1990 ninety is like this ] later versions like yours have that seal and hubs rely on just grease [ when rebuilding older types some grease is used to start with ]
Your seal in the pic is fitted the correct way with the spring facing out..
Some folk do not bother with this seal making the hubs lube the old way However with the older system you do have to have good seals/lands in the hub outer position [ seal nearest the diff ] to keep the oil in and to check diff level as this feeds the hubs.

Well that’s got me thinking. If the spring is on the outside, away from the bearing, is it’s purpose to keep diff oil out then ??
The bearings weren’t dry when I removed the hub, but they weren’t exactly well greased, which made me think it was losing grease !!

It is to keep diff oil coming down the shaft from going in the hub, I and others think the old system was better for the life of the bearings and some with the later type leave that seal off.
If the hub outer seal has gone bad some grease will escape, just not as quick as oil
