Rear axle seal (o ring) leaking? Contaminated brake pads
Hi everyone, I've found that there's differential gear oil contaminating the brake pads on one side of my D2. I ordered an o-ring from Atlantic British - Item:FTC4919 - which I believe is the right part, corresponding to part 2 in the diagram below. I'm not sure this is what's causing the leak, but I thought I'd check here to see if this is a very common issue and would most likely be the source of the problem. I bought brake pads as well that I'll use to replace the contaminated ones after resolving this issue. There was a time when the vehicle swung a bit on the highway when I needed to brake a bit more urgently than usual. I cleaned things up and that's helped a lot.
I've also planned to refill the differential after draining it as soon as I've done the rest of the work here. I should be able to replace the o-ring without draining the differential though, right? I'm also wondering what gear oil others here would recommend using.
I appreciate any input.

I had a period of time where I was having trouble getting that seal to seat properly; ( I had some burrs from cleaning corrosion on the sealed wheel bearing unit which I couldn’t seem to get right the first time. Or the second time) so I had replaced it about 3 or 4 times in a very short time -
so if you haven’t flushed your diff fluid in some time, now is a great opportunity to flush & replace.
That said, once I’m disassembled to the wheel bearing, i can say that I’ve raised the jack to pitch the axle & have virtually no loss of oil while replacing that seal.
I flush my dif fluid more frequently then most would, therefore I just use a Napa brand or valvoline brand synthetic 90/110 weight gear oil

The O ring is the only barrier back there to leak fluid I believe.
the wheel bearing is a sealed unit. It doesn’t contain fluid to leak - nor is the construction of a sealed bearing able to allow passing of fluid.
I mean- your bearing would have to be so destroyed that it would be obvious that a weeping gasket is not the issue to address..
when you remove the rear wheel bearing to get to gasket- you can confirm this by spinning the bearing. It should be silky smooth. If there is play / then replace the unit.
get a cpl o rings, they’re cheap. You shouldn’t have any problems changing it.

Your rover should provide you with plenty to service - no need to get into anything unnecessarily.
