Removing water from rear diff

[Ellie]

Hey,

I recently went through a very deep creek crossing that consumed everything electrical inside my car, needless to say, my diff filled up with water

I know this must have happened to others before so I'm wondering what did other find was the best way to get it out? I plan on pulling off the rear case and spraying the inside with Methylated spirits and then blasting with an air compressor a couple of times.

And yes, as soon as this is done diff and gearbox breathers will be fitted

That's about it or use WD40.let it dry out and refill it

when it comes to engine oil, and water in with it, water sinks to the bottom, is there a drain plug at the bottom asks guilty of never replacing diff oil in any subaru

It'll go milky if theres any water in it. so drain it, top it back up and check how it looks after a couple of days. Might be worthwhile extending the breather if you plan on going swimming every now and then, you can go cheap and cheerful or I'm sure someone would sell a kit;

"For rear diff breathers, remove the existing breather top, file away the lip on the breather stem then fit garden hose (or similar diameter hose) over and tighten with a screw up clamp. Then cut a slot out of the diff carrier above the breather so there Is clearance for the hose, and run the hose over to the RHS rear panel. Use a wiring loom grommet to fit it into the rear panel, loop the open end and cable tie a piece of foam over the end. " (stolen from the internet)

Thank you all for the relies, I thought I was on the right track but thought I would ask anyway, also,

This is excellent for a guide, thanks Weegee
