Review on Enhance Your Vehicle's Performance with the Dorman 600-105 4WD Actuator for Ford / Lincoln Models by Johnathan Delic

Works great. The old one on my '04 F150 didn't work at all due to water issues in the actuator and solenoid, replaced both and now I don't always have that hub on and spin the axle like that. I couldn't tell this part apart from the original other than that it clearly worked. Easy swap, about 30 minutes, there are some good YouTube videos explaining how to do it.
