I'd be more tempted to suspect it's got water in that has washed out the grease and left it dry, but you can tell much better with the hub sat in front of you than looking at ap icture on 't'net.

I think RRB is probably right. The "lubricant" that failed to keep my bearings going looked more like used engine oil than grease.
stretchy:
RRB this is what I was saying that becase the diff oil was able to leak into the hub it just gives that bit of extra life to the bearing rather than drying up and welding to the stub. thus . is this hapening becase of under filed diffs ??
Range Rover Blues:
Ahh, I think I get you now, if you keep replacing the diff oil that leaks out,it will keep leaking onto the bearings and keep them oiled?
Well as long as the bearing is wet with something to keep down what little friction exists (and keep the surface cool) then yes, I guess they "should" be ok.
The ones I change are either rusty (makes a droning sound) or the grease is drying up, but TBH I put new bearings in when I do the brake sisks, at the very least I clean them out and fill with new grease.

well had lots of fun with wheel bearings today,
i done the drivers side 1st and all went very well. nice new bearings and seals.
then came the passneger side, lots of movement so i suspected it was going to cause me some trouble, i undone and removed the hub cover and all the outer bearing had fallen apart. the 2 large nuts was loose and had no thread left on them due to them being batterd about by the bearing rollers rattling around.
managed to get the hub off and found the remainder of the outer bearing and an intact inner still stuck on the stub axle.
both came off with a little work from the puller.
so after closer inspection i have found that the inner part of the thread on the stub axle is now no longer there and also some nice deep marks on the stub axle surface,
so i wont be getting my disco on the road this weekend now as i have to sorce a new stub axle, gasket / 2 new nuts / thrust washer /
what i need to know is its fitted with 24 spline axles, so would a stub axle from a 10 spline fit or are they different.
also from what i can make out theres a needle bearing inside the stub axle with a seal, going from the workshop manual,
do these come fitted to a new stub axle or would i need to buy and fit to the new one.

There only appears to be one part number in the catalogue, so I'm guessing they're the same.

I had to order mine separately. There is also a brass bush on the inside of the stub axle which can be a bit of a pig to get off. It might be worth buying a new one of these too. If you go with re-using the old one then make sure you smoothe off any marks you make when removing it from the old stub. It might be quite awkward to start this bush moving to remove it but once you've broken the stiction between it and the axle then it'll prise off easy enough.
If you've removed the stub axle I would also consider replacing the mud shield (metal ring that came off when you undid the 6 bolts holding the stub onto the swivel housing) as that is what the seal in the hub works against to keep muck out of the hub bearing.
Have fun :D
