I don't know the specifics for a fourtrack

so this is more generalised reply

all 4x4's can wade up to axle without any modification. (halfway up wheels)

Then it depends on where the breeders are for axles, gear box, transfer, engine.

most jeeps will have hoses that extend the breeder holes upwards

But these rubber hoses can come off or perish over time. so if you plan going wading higher than axle check that they are in place.

it may be difficult to find breeder holes / tubes for gearbox and transfer as they are often on top gearbox next to body.

Worse case if you do go too deep the fluids will become contaminated with dirty water and cause damage over time.

The big stopper is the air intake for engine its usually about headlight height
suck in water there and your engine will possibly be damaged beyond repair.

To equip your 4x4 to wade deeper you would put snorkel on engine air intake and raise up all the breeding tubes.

solid axles have a breeder valve usually on one shaft about mid way from pumpkin to wheel. The reason for the breeder is that as the oil heats it expands pushing out air and when it cools it contracts sucking back in a little air.

once the engine is left running the exhaust will look after its self.

personally on mine I only wade up to bottom of door as I like my carpets.
