Should be able to unscrew it from diff housing, give it a clean with degreaser and flush it out, blow some air through to check and screw it back in, Regards Frank.

Hi,
I had the same problem on my defender, and it was the breather, when I unscrewed it, it was full of crud and corruption. There is one small hole going across the fitting, which I opened up a tad, and punched right through. That was only a few months ago, so no long term report available.....Gumnut

I ended up changing mine with diff breathers located in my engine bay.
Small cost and piece of mind knowing no crap will get in there again.



Not a great pic but you get the idea.
As said above. Just unscrew from the diff housing.
Front ends around the firewall and back ends around the diff well.
I found the old hoses get hard and cruddy so thats why i replaced.
Filters are a good idea and mounting in engine bay for piece of mind.
