Water In Diffs ?

[HeyCharger]

My tandem diffs make water - great if you are caught short in the desert!

I'm not joking. I park the old girl under cover, but every couple of months I can drain probably about 1/2 cup of water from each diff.

How does it get in there

I think there is a vent up the top which I may hook up to some silica-gel.

Any thoughts?

Thanks. Rod.

How's it going, make sure your vents are working, I had to take mine out and blow air thru them to unplug them, If you still have water in the rears you must be parking where it's real cold at night and warm during the day and there making condensation. That can be solved by driving more often and internal heat will dry up the water. Small amounts of water in large diff's is very common on heavy equipment that sits alot.

Good Luck, E.S.D.

Don't seal up your vents. When pressure builds enough it will leak gear oil out your wheel seal or pinnion seal.

Thanks Guys. Yes, I think it must be due to condensation.

I think I will arrange some plastic tubing that connects the vents to say a jar that contains silica-gel (it adsorbs water readily, making it useful as a drying agent).

I have thought of doing this to the fuel tanks too as my old girl sometimes sits for months before new fuel is added. I do get a lot of water (condensation) in the tanks.

Obviously I would remove all this "prior to flight".

Thanks. Rod.
