Oil Leak

Hi All
Please excuse my total lack of technical knowledge, but my manual hasn't
arrived yet!
While showing my truck to my Disco owning father-in-law today, I noticed
some oil on the chassis. Looking a bit further underneath there were some
oil 'splats' (technical term) on the rear of the chassis and the rear axle.
So, once underneath the leak appears to be coming from the transmission. It
looks like coming out of the bearing/seal where the front propshaft comes
out of the centre diff (?) or transfer case (?). Am I right in thinking
this isn't too big a job to replace, or am I in for a shock?
Any comments / suggestions would be greatly appreciated.

Hi Mark
Should't be too much of a problem. Disconnect the propshaft, drain the
oil, take off the flange (might need a puller)remove the old seal and
bash in a new one. A bit simplified but you get the idea. I should wait
for your manual to arrive. Let me know what the manual is when you get
it to see if it's better than mine and I might order one myself. I
wonder if it may be worthwhile changing the other propshaft seal at the
same time. My front diff has a slight weep where the prop goes in but I
will just leave that and see if it gets any worse.

If it=92s the seal on the ftx case where the front prop shaft is connected
then ...
Mine was leaking there 2 and a very slow leak as in a couple of drops a
day
If u check the level of oil on a regular basis (and as mine was such a low
leak it never seemed 2 be a n issue regd dropping the level)
If u need 2 replace it=92s a biggiesh job (compared 2 the other stuff I'd done
in the past) so I let Robbie at it. He already had a 2nd tx case that was
out so got new bearing (as u're at it) and new seal etc..
So with all that stuff done he had he changed within 1-2 hrs.. If it was
just me I'd suspect it would have taken me most of a day (as not done that
b4 and would have 2 go read manual, pics, websites etc..)

Thanks Rod / Brendan
I'll check the levels and see how it goes! It just looked a lot with the
splats to the rear. I have been using the motorways quite a lot so it is
obviously being blown backwards.
Without wanting to go over old ground (I can here the groans already), I am
getting approx 22mpg around town (very hilly area) and about 24 - 25 on a
run. Does this sound OK or do I need a tune up or something?
As you can probably tell, I'm no mechanic, although mechanically minded and
am trying to decide whether to do my own servicing, but am a little
reluctant to finish the full Toy service history.
I also seem to have developed a vibration under load at between 65 and 75
mph. A CV joint possibly? What's the best way to check for this? Also, if
I change the joint, do I need to get the prop re-balenced?
Questions, questions, questions.

Hi Mark,
If it is just under load it is most likely the Universal Joint on the end of
the prop shaft, check both front and rear props.
Best way to check is to put the car in neutral then try twisting or rocking
each joint - normally this will show up most issues, although it would help
better if you can jack up one corner, put the car in park and then get someone
to rotate the lifted wheel whilst you hold your hands around each joint to feel
for movement.
I've just replaced a UJ on my front prop which seemed to get into two
positions, one where it didn't vibrate much and one where it whould vibrate
from 40mph upwards - before I went on hols I checked all the UJs by hand trying
my hardest to get some movement, but couldn't.
For a while now I have had quite a positive thunk when going from drive to
reverse, but handn't noticed that much of an increase in vibrations or noise.
Obviously it was only when we were fully loaded at 1.00am in the morning
heading up the M5 to Scotland that the vibrations really started to kick in.
At one point we stopped up near Glen Coe and driving around a car park I
noticed that if I put the car into reverse and then back to neautral and
checked the UJ it would move around, if I put it into drive and then back to
neutral and checked the UJ and I couldn't move it by hand.

Thanks Julian. The truck is in this week being repared after the break in
(just imagine what the =A3300 excess could have been spent on!)
I will check the UJ's on it's return.
It's funny, but you hear Landrover owners talking about Japanese vehicles
having no personality. I can only speak for myself, but I'm really missing
the old girl!!! Sad or what?

Well after much jet washing and degreasing I finally managed to figure
out where my killer oil leak is coming from:
There is a vacuum pump at the bottom front of the engine, which has an
oil pipe going into the block (RM172E EM-53, a million thanks to
whoever it was that posted links for downloading manuals). The pipe
has been worn and hammered until it fractured, leaving a leak like a
fast-dripping tap.
Q. What has worn and hammered the pipe until it fractured?
A. The banjo bolt on the end of the steering pump pressure tube (Rm184E SR-38).
The pressure tube has been disconnected from the pump and reconnected
to an extension pipe to drive the Milemarker Hydraulic winch. This has
been done in a rather inelegant manner, with nothing to stop the heavy
banjo bolt/winch pipe connection from bouncing around except a
cable-tie onto the chassis. Consequently Iceland's incredibly
corrugated roads turned it into a hammer, fracturing the adjacent oil
pipe.
I can't fix the oil pipe myself, so will have to get it to All
American or a Toyota garage. Anyone know if I'm likely to do damage by
driving with the oil pipe fractured?
Thanks,
