ABOUT ARB 170112: The ARB Differential Breather Kit is designed to provide a high-flow, zero back pressure, zero vacuum breather system to keep your drivetrain free of water. This is achieved with a central high-flow air filter and manifold that will allow up to four drivetrain assemblies to be vented to one central location, positioned high enough to avoid water during crossings.

CONSEQUENCES OF NOT HAVING ARB 170112: When drivetrain assemblies such as your vehicle’s differentials, gearbox and transfer case heat up under normal operation, the air inside expands and increases pressure, not suitable for the vehicle. The ARB Differential Breather Kit is designed to provide a high-flow, zero back pressure, zero vacuum breather system to keep your drivetrain free of water.

HOW DOES DIFFERENTIAL BREATHER KIT WORKS: It uses a central high-flow air filter and manifold that will allow up to four drivetrain assemblies to be vented to one central location, positioned high enough to avoid water during crossings.

A differential / axle breather serves the important purpose on a 4WD vehicle of venting the air pressure in drivetrain assemblies such as the differentials, transmission and transfer case.

The differential breather Kit is designed to eliminate the factory breathers shortcoming by providing a high flow, zero back pressure, zero vacuum breather system.

The differential breather Kit is unique in that it uses 8mm tubing (where most other kits use 6mm tubing).

【Comprehensive upgrade】The unit has been improved with the new design of the new 4WD front axle actuator and disconnecting components. It used a superior shell Gadus S2 V220 synthetic lubricant that will withstand more abuse than your old lubricant.

The 4WD axle actuator housing, also called axle disconnect housing, is part of differential that houses the gears and shift fork required to lock both front axles together. It works together with transfer case to send torque to all four wheels. Most of the time, the vehicle is in RWD.When 4WD is engaged, transfer case engages the front driveshaft. It’s still necessary, though, to connect two front constant velocity (CV) axle shafts. This is done via a front differential and the axle actuator.

Due to its location underneath the vehicle, the axle actuator housing can be exposed to dirt, road salt, and other pieces of road debris. These can damage the actuator housing, which will make it less effective at protecting the moving parts inside. Then, dirt can get inside of the actuator to cause bearing wear or lubricant leakage. Wear can also simply occur over time from use. If you try to shift the vehicle into 4WD at speed, the high forces involved might crack the actuator housing.

This 4WD AxleAactuator Housing Fits for the Following Vehicles: 2004-2007 Buick Rainier, 2002-2009 Chevro-let Chevy Trailblazer, 2002-2006 Chevy Trailblazer EXT, 2002-2009 GMC Envoy, 2002-2006 GMC Envoy XL, 2004-2005 GMC Envoy XUV, 2003-2008 Isuzu Ascender, 2002-2004 Oldsmobile Bravada.
