Key features

• •The four-wheel drive axle actuator housing, sometimes called the axle disconnect housing, is part of the differential that houses the gears and shift fork required to lock both front axles together. The axle actuator housing contains and protects the shift fork, locking collar, and gears. Those moving parts need to be protected from the elements and kept properly lubricated.
• •The axle actuator housing is found on the differential. It works together with the transfer case to send torque to all four wheels. The transfer case connects the input from the transmission to the rear and front driveshafts. Most of the time, the vehicle is in rear-wheel drive (RWD). When 4WD is engaged, the transfer case engages the front driveshaft. It's still necessary, though, to connect the two front constant velocity (CV) axle shafts. This is done via a front differential and the axle a

• •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. If you try to shift the vehicle into 4WD at speed, the high forces involved might crack the actuator housing. This Assembly fits 02 03 04 05 06 07 08 09 years.
