WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

If installing new components, there is no reason to remove the seals from the old components.
The differential electronic module (DEM) and solenoid valve are calibrated together and must be installed as a set. If installing a new DEM or solenoid valve, install them as a set only.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .
Disconnect the DEM by pushing the connector tab through the slot while pulling the connector out.
