Get four-wheel drive engaging on demand with the Standard Ignition 4WD Actuator TCA105. This actuator drives the mechanism that shifts the front drive components into engagement when you select four-wheel drive, then disengages them for two-wheel-drive operation. It fits the 2000-2005 Ford Excursion, the 1999-2010 Ford F-250 Super Duty, the 1999-2010 and 2017 Ford F-350 Super Duty, the 1999-2010 Ford F-450 Super Duty, and the 1999-2011 Ford F-550 Super Duty (All engines).

  • Function: actuates the front-axle engagement so the system shifts between 2WD and 4WD as commanded.
  • Direct-fit replacement for the listed Ford applications — one per vehicle.
  • Swaps in for a worn or failed original 4WD actuator.

Signs this part may need replacing include four-wheel drive that won't engage or disengage, or a 4WD indicator that flashes or won't set. These symptoms can have other causes, so diagnose the system before replacing; if a failed actuator is the cause, this unit replaces it.
