Toyota Axle Housing Breather Extension

Why would you want to modify a Factory Breather? Simply put, the stock breathers will not keep water out when submerged. Normally you would use just the factory breather...until you go through a river or mud! Plus, when a differential cools down it creates a vacuum due to the cooling effect...who wants to vacuum water in their diff? Protect your differential by installing these breathers and adding on your own section of tubing available at most auto parts stores.  Its a cheap and easy trick to add protection to your differentials.  Much easier than re-tapping your differential, just remove the factory breather and screw this one in.
