Thread: replacement front diff breather Disco 3 and 4

Yes.. that may be the case. Perhaps it’s also few running them into cold water (shock) which will contract quickly!

Wondered what that was when changing coolant bottle yesterday

Don't delay doing this job people, I just cut off my old filter and heard a big suction sound come from the pipe. Poor diff was starving for air. Off to the shops for a replacement.

God knows why I left it so long, even though the filter looks clean inside I couldn't blow or suck any air through at all.

At least you know the diff seals are working!

Seeing as mine was clean, I'm going to track down the rear and replace that too. I can't see how it's any different, most likely completely blocked.

Let me know when you find it

Me too. I went looking and it seems to be around the fuel filler, but it appears you need to remove the wheel arch liner to get to it.

Anyone else managed to find the rear diff breather or the transfer case breather?
