You may have said it "100 times" but this is the first time I've read anyone stating to KEEP the IWE system. I, for one, have always been a proponet of the IWE, despite the sea of others declaring it all "junk" and to remove them entirely, even if there are no issues. It's rather a simple system of an electrically operated solenoid valve, vacuum lines, and IWE's. Sure, a failure at the most inoportune time of any of these components can make an otherwise fabulous outing a bummer, which so happened to me last year out in the desert: solenoid valve failed and stayed in the 2WD "vacuum" setting whenever powered. If I'd known at the time it was the solenoid valve, I would have simply disconected the electrical connector (or vacuum line from brake booster) to the solenoid to get the IWE's engaged into 4WD.This the first and only time I've experienced any failure in the IWE system over the 25 years I've owned 4x4 F-150's/Raptors, but I'll still always keep my IWE's intact on current and future Ford trucks.
