Diff breathers extension in 80 series

I went to do mine , its a poverty standard. Lay under the back scratching my head. Even with photos I couldnt find the appropriate points. Went back inside and suddenly the light bulb went on. It already had a diif extention system, factory by the looks of it.

Main question I guess is to where to extent it? With front axle it is very simple – somewhere under bonnet. Rear breather is already 5 cm or so below body. If I like to extend it say 40 cm more to where I can put this hose?

There is a reasonable article about doing this on the LCOOL site.
I did the front, back, transfer box & gearbox - it was not too hard to access the breather pipe at the top of the gearbox.
I ran the new rubber fuel line for the back breather through the chassis rails, coming out of the rails near the transfer box to connect in a T connection for the transferbox / gear box etc.
I used the original front breather (open all the time) for the new set up but mounted it high up - close to the bonnet on the pasenger side.
All up it probably took a couple of hours & cost mayber $40 - 50 dollars. Used all brass 1/4" T fittings.

Hi KSV

Run both to the engine bay, it is much easier to tell if they are blocked from there then from underneath ( plus not much point having them above the gearbox as its not much higher than the diff). Clear hose works better for checking blockages also.
A good mechanic will remove the hose during service and blow some compressed air through to ensure the check valve is still functioning ( not towards the diff ! )
Allow some slack for suspension movement. It is suprising how many can pull of the diff hose stub from suspension upgrades.

Rear breather can be run along the chassis rail, up the side of the right rear wheel arch and through a purpose cut hole inside the intrerior panel.

Just remove the panel and you'll see the hole. It has a rubber grommit in it.

Did this to mine and it's perfect.

I ran my rear breather along chassis rail through grommet in bottom of L/H guard and up into the compartment that holds the Jack and cable tied end behind fuel filler inlet
easy to access
Hope this helps

Thanks everyone for ideas.
