Does Not Fit '97 Ford F-150 4x4

      Comments about Dorman - OE Solutions 4WD Vacuum Actuator, Front Axle:

      According to Dorman, this part (Dorman 600-300 4WD Vacuum Actuator/Motor) is supposed to fit my 1997 Ford F-150 4x4, but it does not. In fact, there are two separate problems that keep this part from working correctly.

      1. The distance from the plastic shoulder to the E-ring groove is too small. This means that when you install the shift motor, the E-ring groove is not visible because it does not come all of the way through the mounting tab, and thus, it is impossible to install the E-ring. This E-ring is the retaining ring which is intended to hold the motor on the differential. Without it, the motor will fall out, and in fact, will be pushed out every time you shift into 2WD. The ONLY way to make this part fit the differential is to grind the mounting tab on the differential down so that it's not as thick. Grind it just enough so that the E-ring groove is visible and so that the E-ring can be installed.

      2. The second problem with the fit of this part is that the travel is not sufficient to pull the front differential into 4WD. The only way to fix this is to heat and bend the shift toggle about 1/8 inch (toward the driver's side of the truck) so that the motor will rotate the shift toggle enough to engage 4WD. Without that modification, the shift motor will not pull far enough to engage 4WD in the front differential.

      I was able to modify these parts on my truck so that this item works, but you should be aware that without these modifications, the part will not work for this make and model truck.

      I should point out that I have used numerous Dorman parts for various vehicles over the span of several years, and until now have had no problem at all with them. Generally, when Dorman says they fit, they fit perfectly. In this case however, the part does not fit even though Dorman claims that it does.

        The part works but you have to file plastic down to fit. Does not come with new rubber shaft cover or the snap ring.

        Comments about Dorman - OE Solutions 4WD Vacuum Actuator, Front Axle:

        This item is made of a very fragile plastic "as is the original one". It's location is on the front of the front axle where it is most subject to recieve damage. It is covered with a very flimsy plastic cover which offers no real protection. This is not a fault of Advance, but it would be nice if the replacement part was made of metal. At least the small plastic cover should be replaced with a metal one.

        • Q:

          Is there a trick to removing or installing this actuator? All that I see is a snap ring, which I removed, but the old actuator will not budge.

            A:

            Removal Procedure: Raise the vehicle and remove the front differential carrier shield, if equipped. Then disconnect the electrical connector from the actuator. And remove the electric motor actuator by turning the actuator counterclockwise. Installation Procedure: Apply sealant to the threads of the electric motor actuator and use the correct sealant. Then install the electric motor actuator. And tighten the actuator to 20 N.m (15 lb if). Connect the electrical connector to the actuator.

            A:

            An actuator typically is a mechanical device that takes energy, usually created by air, electricity, or liquid, and converts that into some kind of motion. That motion can be anything from blocking to clamping to ejecting.
