    Question LT230 leaking at the rear - but where from?

    The LT230 in this MY03 D2a has a constant oil leak dripping down when sitting. This is the accumulation of the past 12 hours:



    The leak is on the rear end of the transfer box - is this likely to be from the rear output seal (and possibly damaged/failed bearing with it)? The Google search results indicate that if it's the rear output seal then it should be coming through the handbrake drum rather? But this seems to be dropping down between the back side of the transfer box and the handbrake drum:





    The filler plug and sump gasket look dry and clean.

    I believe you have hit the nail on the head
    It’s a common leak on the lt 230
    Not a hard job to do

    But be warned, it’s a Land Rover

    You perhaps should buy a new rear output shaft flange , unless you want to do it again as I had to. They are pretty cheap at AFAIR $40 a couple of months ago.
    With that much oil you may need new brake shoes also. There is a drain between the drum and the seal but it always seems to saturate the brake shoes.

    Or, as it's the handbrake, you could use the old 'soak 'em in metho and set 'em alight' trick.

    That’s a new oneLT230 leaking at the rear - but where from?
    Never heard of that before, I’ll pass that tip onto my nephew, he is a believer in the easy way out
    His response to any sort of oil leak is to “put some brake fluid in it”
    He swears by it for “repairing” seals in power steering systems
    I call it the TD rebuild (TD are his initials)
    Brake fluid and a can of white knight black spray paint makes it new again 🤣🤣

    Well, we used to do it all the time when drum brakes were common. However, it was mostly to burn off brake fluid soaked shoes when wheel cylinders leaked. It worked fine. Gear oil would be harder, I guess, but I'll bet it would work. No way you'd burn the brake shoes themselves. You could even use a gas torch.

    Thanks. So it doesn’t have to leak through the hand brake assembly then to be the rear output seal.

    Yes, but so long as it stops leaking for long enough to pass the road worthy I can live with that.
