Persistent Rear Diff Seal Leak

Hi,
Looking for some advice. New to Defender ownership. Love my Defender. However. Leaks.

I have a persistent rear diff seal leak. I have replaced the seal twice and have installed a new flange. I noticed recently that the axle breather was blocked completely so have replaced that but the seal still leaks.

Has the blocked breather blown the new seal do you think?

Thanks
Cheers
Ian

Best to ask in the Defender section...

Pinion shaft and/ or bearings are worn
