Good To Know

Q: What causes these vacuum pods to fail? A: Over time, the internal rubber diaphragm can dry out or crack, leading to a loss of vacuum pressure that prevents the 4WD system from engaging.

Q: Does this part include the transfer case cable? A: This component is the vacuum actuator itself and is designed to connect to the existing front axle engagement cable.
