Dorman 600-405 Independent Wheel End Coupler (Vacuum Delete Kit) Compatible with Select Ford/Lincoln Models, 2 Pack (OE FIX)

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.

Perfect fit for my 2013 Ford F150, no more vacuum issues

The best

So I installed these in a 2012 platinum f 150. Installation was fairly easy as I did them in my driveway . They work great however they will take some getting use to . Truck feels like it’s dragging because the front axles are always spinning . My gas mileage went from 15.5 to 12.5 . That’s my only gripe . Greatest thing is I will never get stuck in the snow again . It’s a trade off . Stock actuators are a guaranteed failure .

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.

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

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

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!

What an amazing product , i had a huge problem with 4x4 with the OEM part , loud bang every time i go up hell because the hub are disengaging , threw them away and got me these bad boys , solved all the issues i had , car feels powerful and i feel like i trust it again going hard on it . Thank you for this product really love it and recommend it

These work great as advertised. I just wish Ford Motor company would have redesigned the I.W.E. system to something that doesn't rely on a weak and pathetic spring pressure to engage the hub. The only foreseeable problem is if a cv axle or front drive shaft fails, you now have to drive home very very slowly while it smashes around. This happened to me when the front drive shaft blew. After that happened, I bought a Garmen Inreach gps that connects also to my phone with text messaging via satellite.

Done

Excellent Fit. It was exact fit for my 2010 ford f150 4.6L. I now have 4 wheel drive for snow. Bring on the snow.
