What does a transfer case vent tube do?
Re: Transfer case Vent Hose? Vent is a breather. You will get moisture condensing inside the transfer case, when the oil gets hot enough through normal use, the moisture vaporizes and escapes. Also, hot air expands.
Does a transfer case have a breather?
The breather is located on the front half of the transfer case, on the upper part of it (if I remember correctly). When you remove the bolts that join the back and front half of the TCase, you then will be able to remove the back half housing of the transfer case.
What is the purpose of a diff breather?
A differential / axle breather serves the important purpose on a 4WD vehicle of venting the air pressure in your drivetrain assemblies such as differentials, gearbox and transfer case.
Why do diffs need breathers?
Why are Diff Breathers important? Extended diff breathers are extremely important insurance for your 4WD if you drive through water. By fitting diff breathers, when your diff gets dunked in water it will contract, and suck air in through the breather (as a pose to water through the seals!).
