Same weak IWE

[t_j]

There were gen2 iwe's and hubs at snoball on a truck, didn't hear about any issues on that truck.

if so will be replacing and will that work? or will ford just use up all the old then switch to this anyhow.

Glass half full: it's engineered to audibly notify you (when your blasting the Sony subwoofer) that your IWE is trashed rather than grenade something more costly. Replacing an $80 hub actuator is actually quite easy to swallow (esp when you have a towing bill or the humiliation of being pulled out by a chebby)

By the way, we DO inspect our rigs before we get out in the shiitake so we detect vac leaks before doing some Lewis and Clarke trailblazing, right? Always test it under load on the dirt, blah blah.

I had no iwe issues on my 11 when it was on top perch ~20k miles. With at least 10 dune trips. Dropped to mid perch broke 2 iwes in the sand. 1 cv. Then now 1 iwe in the snow. I am starting to think I need to be on top perch lol

62k top perch miles no clickity clacking

Vigorous 4h usage

Wreckless disregard for 30 second vacuum lock period

If you've seen the amount of shear area on the IWEs you quickly realize how this can become a tolerancing/stackup issue and have a huge range of owners with the issue and some without.

Whatever engineering team did the worst case tolerance analysis should be asked to recheck their work. I'm willing to bet they did not check the amount of spline engagement at full droop while accounting for all the linear tolerances. That becomes pretty obvious when the raptor has more wheel travel, yet the same IWE splines..

Besides this a minor loss in vacuum and the variability of friction in the IWE actuator can immediately cause problems.

I'm willing to bet the fact that this same IWE is all over the best selling truck in the world proved out over engineering analysis. Millions of trucks out there and only 10,000 or so need the IWE replaced? Statistics probably won in this case.

If anything in the drive train system is barely stronger than the IWE I would be shocked. There has to be a better way to fuse the system to protect it from real potential damaging scenarios and not just driving around in the snow (how mine started to go.)
