What does a rear axle vent hose do?
As the axle increases in temperature, the air pressure inside the axle likewise increases. To accommodate the increase in air pressure resulting from this heat, manufacturers add a vent tube to the top of the axle as means of releasing this pressurized air to the atmosphere.
What is the purpose of a differential 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.
What is a differential vent hose?
The purpose of the vent hose is to keep the vent opening further away from the axle tube where there is dirt and moisture (water) that might enter the axle and differential. Axle vents allow pressure inside the differential to equalize with the atmospheric pressure.
What is the point of diff breathers?
Are diff breather kits universal?
This kit is universal and suitable for most four wheel drive vehicles. Vehicles without threaded housings may require 6mm rubber hose and clamps and a small amount of ingenuity to install.
Why do diffs have breathers?
What does a diff breather do? From factory, your differentials are fitted with breather valves that vent the pressure build up from inside the diff when they get hot. The breather lets it release this pressure out into the atmosphere, instead of out via your axle seals.
Why do you need a diff breather on a 4×4?
Where raised breathers become important, is when you’re trundling along with the short-stick locked in causing everything in your driveline to heat up. Wheel bearings, axles, CVs, diff centres, pinions – the works. As the air in your diff housings heats up, it expands, and pressurises the diff.
How to extend Front and rear axle breather tubes?
Here I explain how to extend and relocate your Jeep Wranglers front and rear differential breather tubes using a 5/16″ (7.9mm) rubber fuel hose and your stock axle vents. This cheap and easy modification is a must if you plan on crossing any water. This is exactly the same for all 2007-2018 Jeep Wranglers along with many other 4×4 vehicles.
What makes an axle breather so important in a jeep?
This part is contained in the differential vent and functions by venting the hot gasses that get trapped in the differential breather valve. The axle vent hose attaches to the differential, which enables variable rotational speed of your wheels as you turn. What Makes an Axle Breather So Important?
What does a stock axle housing breather Kit do?
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.
