Flushing Diffs, Gearboxes, and Transfer Cases

Ok, so I have water in my drivetrain. I can drain the contaminated oils out, but what about whats up in the bearings, gears, ect, waiting to contaminate the new oil. Has anyone used anything to assist flushing the drivetrain completely. I was thinking maybe diesel and driving for a couple of hundred metres at slow speed, then redraining, and filling with new oil.
Is there a product available that will do the job?

i'd just go to super cheap and buy the cheapest engine oil and do a couple of km then drain

thats basically what I do, too.
but I use correct, and cheap oil, and do a few hundred k's, then fill with the oil I want.
after draining of course

There is an engine flush product available.
As for diesel in your block, not sure what that would do to it.

By drivetrain, do you mean gearbox and diffs? Prob just do what they guys have said, find some cheapish oil, bung it in, drive round the block and dump it again...

im not sure about diesel in your engine, but in diffs it works a treat, will still protect it enough for slow driving for 2 mins and sloshes around alot more to get all the water out.

Well, I went the diesel route. Drained both diffs, gearbox and transfer case. Both diffs and transfer case had water in them, not surprising really, having sat in 3 ft or so of water for 15 or so minutes. Front diff needs new pinion bearings, so seal has been leaking oil, so thats where the water got in, Transfer case probably through the shifter boot, and rear diff probably through the breather.
Drained all as best I could, warmed from a drive, and let drain for a couple of hours. Refilled to full with diesel, then drove at about 30kph for a KM or so. On return drained the diesel, which came out a nice milky colour, turned out they were all overfull from the diesel frothing. And refilled with new oil.
I think this is the method I will use from now on.
