The 4WD system on certain vehicles fails when cracks in the actuator's diaphragm create vacuum leaks. The diaphragm on this Dorman OE FIX actuator uses a mesh-reinforced rubber material to provide three times the durability of the original design.
This 4WD actuator directly replaces the original equipment part on specific vehicle applications. It is reverse engineered to reliably restore proper functionality.
