    • I can has 4WD again?
Review Image by Adam Adam

I decided to try these instead of trying to keep the IWE system going. Continuing to throw parts at it is a total waste of time, in my opinion. The system itself isn't a bad idea, because being able to stop the CVs and front differential from spinning will save the driver about 1-2 mpg and reduce wear on the axles and differential. Unfortunately, Ford didn't put enough effort into making the system durable. The vacuum lines get holes from heat rot and rubbing, the original vacuum solenoid was an absolute joke of engineering. They did "upgrade" it to be able to keep water out (and thus kept out of the lines that carry it to the actuators, causing rust, and eventually failure), but it's still a cheaply made plastic solenoid. The actuators that these Dorman units replace are far from being "built Ford tough". Again, IWE was a good idea, but badly executed. If your IWE has been non-functional, and you've heard any clicking or vibration while attempting to use it, just save yourself some time and buy a set of hub assemblies while you're at it. You're going to need them. These aren't terribly hard to install but make sure you have heavy duty jackstands and a torque wrench. Look up the torque specs for the fasteners. I used Lucas Xtra Heavy Duty to grease it all up. The 4wd works fantastic now. I'm very glad I did this, and would recommend it to anybody. ... show more

    • Easy installation
Everything needed if you want to eliminate your iwe system. Pretty easy to install and will definitely eliminate the vacuum 4wd. Hubs stay mechanically engaged.

    • Good buy
Works great and easy to install. Great value and fits perfectly. Eliminates the noisy rattle of the original

    • Great upgrade
This fit just as expected and fix a known issue with ford trucks. If you're looking to simply the vacuum system on your ford these are the way to go. One downfall, inherent to their design, is that now your front cv shafts coast all the time. Not a huge deal but will lower mgp marginally as well as add a small amount of extra wear. Definitely for a more experienced installer. Time will tell their durability. ... show more

    • Worked great to solve my IWE grinding Raptor SVT
Worked great to solve my IWE grinding from the leaking poor design of the vacuum actuated original setup on my Raptor SVT. Now 4wd works when I need it. Install was easy. Make sure to shoot some grease inside the fitting!

    • Highly recommend
Excellent product! Save the headache of trying to find a vacuum leak when all you really need to do is delete it altogether. I've heard ya lose gas milage. I'll say this,its sooo minimal that its barely noticeable.

I have a 2015 F150. I bought it used and had it for about 6 months with no issues out of the front end. One day I engaged 4x4 and upon disengaging, a clicking noise started from the front end. It was intermittent at first, then became constant at speed, then developed a grinding noise along with the clicking. I thought my truck was falling apart. Upon further research (online forums and YouTube), I learned what an IWE was and how failure prone they were. I was torn between replacing them with vacuum actuated ones like the OEM, or bypassing the vacuum system and buying these. I chose these and I couldn’t be happier. They fit perfectly, installed easily, and they’ve held up well to regular off-road use. There are plenty of videos online showing installation, but most tell you to disassemble way more than I found necessary. When I changed mine out, I loosened the brake line brackets on the frame, the upper control arm, and the tie rod. That was all I needed to remove to allow enough clearance to pull the old unit out and slide this one in place. My truck does have a 3” level up front, so it might be different for stock height trucks. The grease fitting on this unit means you’ll be able to service this IWE instead of simply replacing it, saving money and preventing damage to the CV axle. As far as MPG loss, I haven’t experienced any either around town or on the interstate. This is a great product that will save you a lot of time and headache ... show more
