Engage and disengage the front axle on command with the Standard Ignition 4WD Actuator (TCA107). This actuator shifts the front axle to engage and disengage four-wheel drive, and it installs as a direct-fit replacement across a range of Ford and Lincoln trucks and SUVs — including the 2003-2015 Ford Expedition and F-150, the 2003-2014 Lincoln Navigator, several model years of the Ford Lobo, and the Lincoln Mark LT.
If a failed actuator is the cause of 4WD that won't engage or disengage, a 4WD warning light, or grinding when shifting into four-wheel drive, this replaces the original unit. Because those symptoms can have other causes, diagnose the system before replacing.
