Review on Dorman 600-560 Actuator Fork for 4WD by Ron Josey

This is kind of a niche product but it works great and isn't as hard to replace as I thought it would be. I bought it for my 2003 F150. It's been slowly shifting into (and out of) all-wheel drive for the past few years. It finally got annoying last winter when my sister got stuck in the snow in her driveway. Finally, I did a little research and found that "centre axis deactivation" is a weak point in the 4WD system. The front drive axle on the passenger side consists of 2 parts with keyways on the ends. This shifter fork slips a ring over the mating ends and secures them together. The problem is that the plastic ears on the fork will break and then the fork will not be able to grab the ring to move it back and forth. handy and have a decent collection of hand tools. It took about 2 hours to complete this project. 1) Jack up the truck on the passenger side and support it with a jack 2) Remove the front wheel on the passenger side 3) Remove the anti-roll bar link on the passenger side from the lower wishbone axle end 5) Remove underride protection, if present oil deflector (3 screws)7) Remove the 4 screws, with where the axle is attached to the axle housing on the passenger side8) Remove the E-clamp, rotate the vacuum motor 90 degrees and remove it from the mounting hole. Secure it out of the way 9) Remove the breather hose from the top of the axle and attach it to the side 10) Remove a large screw over the passenger side axle housing 11) Pull the passenger side axle housing down and off the main axis away housing. Be careful here as there may be loose parts. If the pivot pin tries to move, try loosening and pushing it back. 12) You may be dealing with some loose parts right now. A thrust washer is installed between the axles. don't lose it Pay attention to the cuff alignment. 13) Clean the cavity from dirt. 14) The connector is easier to remove than it looks. Using a small hammer and punch, gently tap the protruding pin in. Eventually the pin detaches from the shaft but remains in the yoke. 15) Pull out the pivot pin and remove the yoke, noting the orientation of the yoke. It looks like it will work either way, but I made sure to match the markings with the ones I removed. 16) Replace the o-ring on the steering shaft with the o-ring from the boot kit and install the entire assembly into the main axle housing. here is assembly reverse to disassembly. Good luck!
