Water in rear end.

The axle housing may have a crack in it at the top of the housing near the spring saddles. This would allow rain water in, but not leak oil out and be easy to miss. I hope I'm wrong though!!!

 

When shops do diff repairs they steam clean the axle housing. Water will stay in the axle tubes unless wiped out by hand.

Check closely around spring perches/saddles for signs of movement/cracks for water to enter.

 

Oil floats on water. If the housings were cracked you'd see evidence of oil coming out somewhere due to this. If there are cracks they'll be under/near the spring saddles though as others have mentioned so look closely there, otherwise I wouldn't worry too much about it.

When you say they were full of water, how much water do you actually mean? Enough to turn all the oil in there white?

 

If you have a Mack/Mack rears that design apparently needs to be disassembled to some degree and re-sealed (with silicone sealant) periodically. Mine losing a wheel seal after every rain for a while 'til Mack dlr finally figured out (4 or so repl seals!).

 

You need to add more fiber to your diet.

 

Will that soak up the water?

 

From the other rear end... oh wait.. wrong forum.

 

I understand, I hear it's a rainy night in Georgia.

 

Not raining anymore, but cold and windy.
