Q: How to replace the 4WD axle actuator housing?
A: 1. Raise & support the vehicle properly, remove the passenger front wheel, splash shield, & then remove the passenger front CV axle.
2.remove the electric axle actuator from the axle disconnect assembly by removing the 2 bolts and electrical connector. The axle actuator has gone through just as many cycles as the disconnect and if the disconnect failed, well then the axle actuator is probably right behind it.
3. Remove the wire harness clip located on the axle disconnect and the old disconnect assembly
4. Remove the new part from the box and remove the protective plastic plugs inside of each seal.
5. The new units are pre-greased internally from the factory, however just like most any seal, it is a good idea to apply a small amount of lube along the lip of each seal with your finger. This prevents the seals form being damaged when the metals shafts slide through them during installation.
6. Install the new unit and make sure it is flush to the oil pan.
