Axle Pressure and Too Much Fluid

Just throwing this out there for discussion.

I was checking both axle fluids for the first time yesterday and when I pulled the fill plugs air hissed out. Fine, that means blocked breathers and explains the drips under my diffs. BUT, fluid actually GUSHED out! The front must have been aleast 12-16oz. The only thing I can think of is that water got in, sank to the bottom, and then forced out the gear oil. But I am not sure how this could happen if both my breathers were clogged shut.

Any thoughts? Were the wee little lephrechauns at play under my rig?

Did the oil look milky? What are you running in your swivel ball housings?

YEah, check for contamination and remove the breathers to check them as well.

No, the fluid was fine. Didn't stink and was not milky. I already removed and cleaned the breathers. Just perplexed!

When a vehicle is driven through or parked/stuck whatever in axle-deep water it is not uncommon for them to draw in water through any opening, i.e, leaky gaskets or around the stub axles or diff pinion. Gear oil doesn't contain emulsifiers like motor oil does so the water doesn't always mix, or maybe can separate over time (not really sure but I have seen it mix and I have seen it not mix too). Sometimes you can crack the drain plug carefully without removing it and let the water drain. Somehow I doubt that is your problem though. Anyway if the oil looks good and there's no water at the bottom, just let it drain to the level of the fill plug and be done with it.

The previous owner might have convereted it to wet bearings which necessitates overfilling the diffs.

Well, I have Disco 1 axles if that means anything.

Actually overfilling is not necessary. The fill/level plugs are over the center of the axle tube and the hubs will get plenty of oil on a regular fill. Series land rover axles come this way from the factory. Nothing hokie about it, the bearings are huge and do just fine running in oil.

Early 90's &110's came that way too. My 110 has just over 200.000 miles on it 130.000 which I've put on and no bearing trouble, touch wood.

See, now that explanation makes sense. That's why "overfilling" didn't make sense to me and sounded hokie. If LR wanted you to overfill, you figure they'd raise the fill plug!

That would be unretarded and land rover is retarded.
