IWE failed today

I was headed downhill and used low range to slow descent and the dreaded clunking shudder began. Later it started again in soft sand,not much load .... To make matters worse the shutter continued after switching 4x4 off(did not disengage even though the dash light indicated otherwise). Shut the Raptor off for 1hr then proceeded to slow crawl out in 4 wheel drive this time without issue.

My advice is do not drive in low range to slow downhill descent because all the weight of the truck is shifted to the front wheels (the weakest link).
Has anyone used a dealer for warranty work on the IWE in San Diego ?

how do i move this to general forum?

Dont know any in you neck of the woods. But I am questioning my local dealer. Had both replaced in Feb this year and now its back getting both replaced again. Along with a ps pump and 2 new front shocks. And I am easy on my ride.

Easy? Not sure I would stand to close to you. I don't like lightning.

Sounds like a vacuum issue. Even when the IWE fails it would still disengage. I bet the vacuum valve is bad.

What's your truck's model year and mileage, upscrazy8? I'll see what I can do to help.

I keep finding these threads popping up and it doesn't give me the warm and fuzzy feeling.

I have about 7600 miles on my 2014.

I go mudding once and a while, but nothing crazy.

Is this something that is bound to happen? Is it a certain model/time period?

You can help yourself by never shifting on the fly. Always stop to shift into and out of 4wd.

Shifting on the fly is a marketing scheme to sell convenience.

I come to a complete stop every time I get into 4wd. I come to a complete stop when I disengage as well.

Good to know I'm doing it right.

Still in love with this truck. Even looking forward to winter (a little) because this thing loves the snow + mud.

Yea unfortunately the iwe gear is a weak link. And having the torsen diff just magnifies the problem. I am working on a aftermarket solution.

If you can find a good solution you are going to sell a ton of them
