Our Disco has a weap at least I think its from the diff seal. The rockers
also have a minor weap so it's difficult to tell. With all the gubbins in
the way of rocker gasket replacement (LPG'd with seperate injection system)
I'm reluctant to do the rocker seal just yet as it's minor.

The most irritating bit is that what ever is dripping the oil on a run blows
directly onto the exhaust and creates a bit of a pong when you pull up....
not to mention the fear of spontaneous combustion.

To replace the diff seal I recall comment of a nut and a special tool... can
some kind soul please enlighten me.

Is it the sort of job you can do on the drive or would you throw in the towl
and book it in to be done along with the next service. I'm not shy of the
work , just very busy and need the car back to A1 for our touring later this
year.

And is there a Disco 300 V8 manual knocking around the web anywhere? It's
one of the few ones I've not got yet.

Cheers.

Lee D.

Get on with it. the special tool looks like an adjustable peg spanner,
you just need summat to hold the flange still. If you leave the diff
in the axle you should be able to get the seal out with the pinion in
place with the usual hacking and gouging ;-)

Not quite sure why you are telling him to remove the diff to replace the
oil seal ???

Simple job Lee. Drop the prop form the diff, undo the nut/bolt that
holds the flange on, prise out seal and fit a new one .Just make sure
you don't damage the new seal putting it in.

Hope this helps

I just reproduced the workshop manual instructions as some people like
going by the book, but if you read it all you'd see I reccomend
leaving the diff in the axle.

If I remember correctly the 96 Disco's had a collapsible spacer on the
pinion to set pre-load and pinion height.
Doing the job the way you suggest is OK as long as you don't over
tighten the pinion nut when re assembling and collapse the spacer
further that may put you pinion height out.
This means that the crown wheel and pinion may not mate ideally and
result in a noisy diff with premature wear.
For me I would do it the way you suggest but be careful not to over
tighten the pinion nut when reassembling.

Yes I saw what you said........ There is no way that the " book" time
for that job involves all that. You don't want to put the poor chap off
a very simple job
