bc i go all the time and never had any problems. know people who have had to leave there with mud up to the doors all day and even overnight with no problems. like i said waste of time to me, but be my guest if u want to. was just my opinion. its stupid to mud any vehicle if you dont expect to be fixing something. depending on how far the hose goes up, if it goes under water it fills up and will have water sitting in the hose until you take off the hose so worse off. if its the stock one the sec you get out of the water its fine.

Definately not a waste. For how easy it is do do, and how little it costs... sure beats rebuilding diffs!
Mostly for serious off roaders who spend lots of time in deep water/mud, the guys with snorkles.

That being said, I've never done it to any of my old 4x4s and I drove them hard off road. Had to replace the engine in my '86 4runner because I hydrolocked it in a creek crossing that was a little deeper than expected, and I fried the alternator in my '90 Hilux Surf from too many deep mud/water encounters... never pulled the diffs to check for water but I never noticed any problems.

How do they know they had no problems? Did the drain the fluid and check it? Same goes for you.

It costs probably no more than $15 to do this and it is preventative maintenance to keep from breaking. I will spend the money now to prevent it, rather than pay to fix a more major problem later.

depending on how far the hose goes up, if it goes under water it fills up and will have water sitting in the hose until you take off the hose so worse off. if its the stock one the sec you get out of the water its fine.
If its the stock one more water will already have entered in it. As soon as that warm diff hits the water, it cools down and contracts, sucking in water. If the same thing happened to a truck with this mod, it would contract and suck in air from a higher point.

$15 fix sure beats a $1000 fix. Plus taking the breather out and installing that hose will help axle seals. Ive blown two axle seals because of the stupid breather rusting up and not opening. I now have a detriot locker, and 4.56s in a $1500 dollar marlin crawler thrid member and custom made yukon axle shafts and i'm not letting water getting inside a breather that sticks one inch out of the rearend ruin a $2000 dollar rear. Its kind of like insurance by doing this mod.:tu:

Extended breathers are ANYTHING but a waste of time. I owned a jeep Wrangler and MANY Jeepers do the same mod. Keep the vent tube up high and it keeps the water out. Once someone takes their truck across water above the diff case and it fills with water, due to a frozen breather. Like someone else said, a $15 mod is way better than a $1000 repair.

I second that, I think somebody needs a nap.

My Jeep Rubicon has the rear breather run up by the fuel filler and the front is up in the top end of the engine compartment - and this was done at the factory. You want your breathers to be above any point that might get submerged in water.

Took me about ten minutes to do this. Have not had an axle seal blow since. Totaled a rear end with a blown axle seal and did not even know my breather was missing until I went to do this mod. First change of differential oil says it all - see pic.

I do not off road and still would recommend this as the #1 inexpensive mod to do to preserve rear differential life to anybody.
