Rear Axle oil leek question

My 1987 90 has been leaking oil from the rear axle ends and when I
previously asked this question it was suggested it was the outer oil seal
that had gone probably due to pressure build-up inside the axle caused by a
blocked breather.
Anyway, I eventually got one hub off (took all afternoon!) only to find the
seals look OK and wouldn't cause the oil leek anyway (the axle is obviously
after 22S08284B) only a leek of hub grease.
As there does not appear to be a seal on the actual drive shaft what stops
oil leaking out of one of these axles/diffs, the end cap? the ones on the
90 are a bit old and loose it's true.
I have changed the breather for a new one BTW, the old one was only partly
blocked.

The only thing stopping a leak in this case is, in fact, the hub cap.

Wish I'd realised, I'd have saved myself some money and a lot of grief and
time.

BTW is the "Parts Book" available on-line anywhere? I always find their
exploded views more use than the Workshop Manual which I have already
downloaded.

I'm not familiar with this beast, but if the driving member at the outer
end of the halfshaft (it's the spline here that allows oil to pass) has
a groove on the outside it may be possible to fit an O-ring which will
seal against the inside of the hub cap.

There was a complete 110 1987 Parts Book around at one time - someone
may have a link to it.

The Hub Cap actually has a raised inner lip which "clips" into a groove, the
new one is a tight fit too on the tapered end of the hub so it's easy to see
it will work as an effective oil seal. Provided it's not old, cracked and
loose that is.

I've been meaning to correct the spelling in the subject line! Done it
at last.

They're designed to last about two years when exposed to sunlight - keeps
the company going selling them.

So what happens if you paint them? They won't see the sun then, mind you,
the sun in your part of the world is a bit different from ours. :)

Blame it on the fact we have two allotments. It's the tools for these we use
the 90 to transport, impossible to keep tools down there, they would walk in
hours/days.

£7.10 for two from our local LR dealer, probably a lot cheaper from Paddocks
etc.

The solvents in the paint probably have the same effect as the sun.

All I need now is a 90 or 110 to which to fit them. Alternatively dream
up a way of modifying the RR to allow their use.

Have you ever tried to get paint to stick to plastic? - except when you
don't want it to. Might be worth trying though.

later RRs have them anyway, on the front at least.

I bought some special silver spray paint for plastic to do my S111 radiator
grill and it's lasted years. Lots of cars now have plastic panels so it
should be easily available at any Motor Factor.
