My dad the super genius mechanic has argued that ford rangers have NEVER come with shift on the fly 4x4 and manual WARN locking hubs. According to http://www.warn.com/powertrain/company_milestones.shtml , Ford announced that its rangers 4x4 models will be equipped with Warn M250 manual locking hubs. A lady came in and the Hubs are broken, and will require replacment but he beleives that the Manual locking hubs found at the local parts supplier are NOT the same and I've reassured him they are. Not only that, but my freinds explorer has EXACTLY the same hubs, and his is straight factory. Its also shift on the fly. will someone please site something that shows that rangers HAVE had WARN manual locking hubs along with the shift on the fly found in this 1989 ranger?
