Seriously they ARE RIDICULOUSLY SIMPLE to extend, hell if you dont put a hose clamp on at the axle, which you should, you dont even need any tools to do it other then a knife to cut the line to size, I dont get what you all are waiting for? 
Even if you do the rear up behind the tail light like I did you only need a philips screwdriver, so two screwdrivers and a knife.
STOP WAITING AND DO IT PEOPLE
yeah that little thing would work but I would worry about it getting ripped, hose would be better I think and it works really, all you need to do is follow the line thats there now

Yeah I understand the ease of extending the lines, but I was just throwing another option out there.... Geez...
As far as the overflow, just pay attention to how much you put in there. I dont wing it on filling engine oil or tranny fluid, so just keep an eye on it I suppose.

All of my 4 wheel drive ATVs use these creeper breathers on the front and rear differentials and they are used in deep mud, water, and snow 90% of the time and never had water get in them or have them get ripped. Never really thought about using them on the Jeep.

Honestly, those expandable tubes look too small. Now I am no differential specialist, but, I know enough about thermodynamics to get me in trouble. I also don't know the temperature differential from cold to worse case operating temperature or the volume of air remaining in the axle housing that will expand during heat up, but I still think you would build up a decent amount of pressure in the housing affecting the seals. A good way to test if the expandable tube is large enough is to put a balloon in its place. If the balloon doesn't get any bigger than the expandable tube would after driving around for a while, then you should be fine. The tricky part will be finding a way not to bust the balloon during testing.

Here is the manufacture's ad:
Prevents dirt, debris and water from getting in to your axle through the stock axle housing breather. Expands and contracts to accommodate increase or decrease in housing pressure. Kit includes one housing fitting, clamp and bellows (as shown). Easy installation takes just a few minutes. No hoses to route. Fits all Toyota Pickup / 4Runner solid axle housings (front or rear).
If it is good for a Toy axle, it's good for a Jeep axle!
Don't forget about your tranny and t-case!
