Review on Dorman 600-405 Locking Hub Actuator Delete Kit: OE FIX for Ford/Lincoln 4WD Models by Adrian Smart

Ideal for getting rid of a loose IWE system. For those giving this a 1 star rating because you thought it was an IWE replacement, you had better buy this. Every F150 owner I've met has had an IWE repaired at some point. You can also delete them so you don't run into trouble. There is no noticeable wear on any parts or worse MPG. For those of you who think this makes you have to drive 4x4s all the time. YOU MUST STILL TURN ON THE DISTRIBUTION DEVICE. It will be like always. It simply removes the middleman when you need to use it.
