It,s probably not actually leaking from there, just that that's the lowest point so will drip from there.

ok just had another look, can't see any brake pipes.

It i can now see a similar drip comming from the bottom of the diff itself    

Its almost dripping at the point were i drew that arrow, the oil is still an orange colour, and very smelly

engine degreaser will actualy clean the diff back to clean metal and make it much easier to see whats goin on  it could be run off from somewhere else. have you tested it compared to the diff oil ie taken out bung?

Not yet, I did see the bung when underneath the car but too scared to take it out!

I tryed some of that Traffic Film Remover on the diff, it took some of the oil off. But some of the incrusted stuff is still on it, i need a presure washer with one of those angeled jets to really clean it up.

Also noticed today its dripping directly off the buttom sump of the diff  


How worried should I be? It seams a very slow leak, only noticed it due to my grandparents shinny new drive. - It was parked in the same place for 3 days and got about 3 spots each about the size of a 5p coin.

There are no noises from the diff, or odd sounds. The ride in the back is still very smooth, and no vibration though the seat on accerleration or general driving.

Whilst it still has sufficient oil in, shouldn't be a prob. When it runs low, BIG prob...

btw, as you know, I have some gunk in garage...

It sounds as though it is hypoid gear oil from the diff - it does smell much as you described - if no nasty noises yet, then probably a seal on the way out and hopefully not too expensive yet.  A few years ago I needed a recon diff fitted to my 2 litre carlton - not too much (~£200 iirc) :-/, but you probably want to check your oil level first, top up if necessary and adopot the old brithish bikers' trip of taking the drip tray around with you .

I don't know how much pain is involved in refitting seals to the meega diff (probably some quite high torque values), a swap might be easier, and I am sure that somebody else would know better......

Yeah cheers, might try some of that to clean it up some more.

I think Gary and others are going to be right, and its a diff seal.

The 2 stub axels that come off to drive the wheels look good, i can see the rubber seals and they all look fine.

So it might be the seal that has the prop going into it.

How easy a job is replacing the seal?? - I hope you can get one from Vaux withouth buying a whole new diff!!

From the photo I think it is the pinion (input) shaft seal. The oil will be thrown outwards by the rotation of the propshaft and will coat the floor pan and exhaust in line with the prop shaft - diff flange.

Give the whole area a really good clean and you should be able to see where it is coming from.

I will try to post the guide to changing the seal tomorrow.

Cheers for that, might borrow some JUNK of Jaime and see if that brings it up.

Cheers for that, although it looks way past my skill level

At your age it shouldn't be, at my age yes.

But I understand what your saying, it's always nice to have some support on a job like that.

I wonder if anyone has changed a diff seal in the camping area of Santa Pod

There you are then, the perfect solution.
