Standard Ignition 4WD Actuator P/N:TCA150
Standard Ignition TCA153 4WD actuator for the 2014-2018 Ram 2500 and other vehicles helps the axles engage for four-wheel-drive operation.
A truck that stays in 2WD, or hubs that will not engage, can mean the actuator diaphragm has failed. These signs alone do not prove this part is the problem, since a leaking vacuum line can produce the same symptoms.
The 2014-2018 Ram 2500 and the 2013-2018 Ram 3500 each take one of these actuators. It is a direct-fit replacement for both, designed to meet or exceed OE performance.
