Water in front axle / differential ( below )
Much later in the trip a heavy river crossing resulted in water seeping into the front diff. How it happens is a mystery to me as i have diff breather extensions and there can be no pressure difference as i have fitted fuel filters to the end. It's apparently caused by hot metal contracting as it meets cold water and water is sucked in . Thankfully no damage done as we only did a short distance in four-wheel drive after the crossing but i will be checking this far more often now
filter very good idea!
another story!
The water was so deep that at the midpoint of the crossing, the nose of my lifted Cruiser dipped below the water. A Landy that followed me had water running into the cab via the vents above the bonnet. My breathers are factory standard and I did not get any water into the diffs or gearbox. Best remedy I think is too stay away from deep water as it gets into lots of other places: alternator, headlight units, fuse boxes etc.

Possible procedure to follow:
- remove the existing breather,
- fit suitable hose (in my case, BMW's high pressure rubber fuel lines - can't be squashed and is oil resistant),
- from rear diff, route pipe along chassis (making sure that you have sufficient slack to allow for suspension travel),
- T-up with similar lines from gearbox and transfer case,
- route pipe up the firewall to just below the bonnet,
- fit simple R 9.95 in-line fuel filter and let the filter hang downwards
On my vehicle I have a separate breather for the front axle to reduce the amount of plumbing (comes up to the cranking battery
