    Hello FRF friends!

    About six months back I purchased my second Raptor (I wanted the Roush) \and the IWEs have been giving me hell! At 7K miles I noticed when climbing the sand dunes that my IWE (left side) was popping and inhibiting me from maintaing speed while climbing a dune. Took it to Ford for warranty work, sent me away saying it was "normal." Went back to the dunes and it got worse, much worse. Went back to ford and they acknowledged my issue (you could just put it in 4x4, drive straight and you could hear and feel it popping while mildly accelerating). The mechanic said it wasn't the IWE as he inspected just the front side; it was my transfer case, so they put a new one on and sent me on my way.

    Went to the dunes and same ol' shit. Went back and expressed that it was indeed the IWEs and had them take the driver side apart. What did he find? The backside of the IWE solenoid was cracked. They replaced half shafts on both sides, and IWEs on both sides. Problem solved! Until yesterday... Went to the dunes, was climbing up and POP! The driver side IWE blew out again. Might I add I'm not by any means trying to place my truck under massive amounts of stress or load, I just really want to use it for what its intended. The hill wasn't even that large, just a lot of loose sand. I'm going to take it to Ford tomorrow, but my concern is that the HP/torque contained in the Roush cannot be maintained by Ford's IWEs.

    ….So the story continues, I figured I’d wait to post to a thread and have been adding to this story as things progress. Ford replaced the IWES mentioned above (a second time). Today I went to the dunes again (two month since last episode), which are the general terrain in Southern Utah. We had a great day without issue, that is, until it was time to leave. I packed up the dog and my son and was headed to the paved road. To get there you need to build a little bit of speed as it up a hill. Got almost to the top, gave a little more gas and pop pop, IWEs blew again ( I feel like if the wheels spin just a little bit under torque they blow). Had to reversed down, 4X4 quit engaging, sank in the sand, and I was pulled out by a Duramax, thus my bruised ego (everyone laughed at the Raptor’s performance). I have a hard time wrapping my head around this. I have much experience off roading but the Raptor hasn’t been living up to its name. I have a built 2004 Expedition with almost 200k miles that does better at the dunes than this thing. Anyway, does anyone out there know of anything aftermarket that might withstand tolerances a little better for the Roush, or do I need to keep blowing these things up until ford provides a better option? Thanks for reading!

    Hey Rick,

    Thanks for the post, I took a look, seems fairly straightforward and simple, do you use these? Even in deep sand? I appreciate the insights....

    I figured if I was to do such a thing I would warranty the current ones then put em on, wonder how the mod effects warranty as well, I also wonder whats happens to the vacuum lines when doing this (how it engages and disengages 2wd vs 4wd) and what kind of additional strain is put on the t-case and tranny?

    The description does seem a bit vague on their website, guess ill call them and get more info...

    I do not. So far I haven't had IWE issues, knock on wood. I was just browsing SDHQ site the other day and ran across those then remember them when I read your post.

    I would think that if you added IWE deletes that anything in the front drive system would be void if you wanted too make a warranty claim.

    The IWE is sensitive and I typically blow one or two a year. But, yrs you are correct, once you put them under load, they crack. It's only plastic taking all that torque.

    There is done things you can do to try and increase the longevity of them.

    1) always let the truck run for 30 seconds or more when you start the truck. This ensures the vacuum system has disengaged the IWE.

    2) never shift on the fly. Always slow to a crawl when engaging and disengaging. And keep the wheel straight.

    3) never full lock the steering and power the truck while in for wheel drive.

    4) ask your dealer to check your vacuum system. Sometimes the valve will go bad and you are driving around town with the IWE engaged.

    Lastly @HAYNES OFFROAD is working on a stronger IWE that might work well for you. Again, I think it may void warranty on other components, but not sure since it will engage and disengage like the stock IWE. I'll see if I can find the thread.

    Are you getting a lot of front wheel slip? I wonder if the front wheels breaking traction could be causing the IWE issue? What tire pressure are you running at the dunes?

    Must be so annoying...Were you with other Raptor that passed the dunes without problem ? Quite scary to hear that, cannot believe our trucks have such a weak point on a so important part of the transmission...

    Is this possible that the IWEs may not be fully engaged, thus causing the system to pop and/or break ?

    Edit : From another thread on FRF : My friend's daughter's F150 had an IWE failure and when he measured the vacuum in the lines, the failed wheel-end had improper vaccum. I think the IWE failures is more of the effect than the cause.
