Torsen front axle problems ! anyone else ???

[Yukon Joe]

I was using a custom tune on my Raptor, a 91 octane performance tune. IWE would make loud bangs and pops right after 4 wheel high shift (driving about 8th of a mile) Decided to try to set back to stock tune as I figured the change in gearing might be causing additional strain on the hubs, I was right, as the issue completely went away.

I'm curious how many of you are/were using a custom tune on their Raptor? I will be a lot of you are/were!

Am I wrong? Reply and let me know because again, this did fix my issue. These custom tunes (the one i was using) did in fact put way too much torque/pressure on the truck. Again, chime in!

I don't think that is the issue. Just a coincidence.
I just started running a tune this summer, and had issues before as well as after.... starting to think it's user error, hahaha

I keep wondering . . how many people engage, "In-Out" of 4 WD under a 'No Load' condition.
Engaging Not under acceleration and Not under deceleration and give 'time' for engagement or disengagement.
I'm thinkin' - 'hookin' & borin' coupled with impatience starts the 'breaking process'
Not saying that the system could not be a better design.
Just saying that it is not a design for . . "Cowboy Action"
Which ultimately means - it should not be on the Raptor.

When mine was broken, I still had issues with it even after permanently engaging the hubs/coming to a complete stop to shift to 4wd. Now even "fixed" I've had it pop out completely twice while turning.

So before I plop down 58,000$ for a 2014 Raptor, did Ford change ANYTHING??

Well... Mine seems to be fixed. No one knows what fixed it besides a lump sum of $ though.

When you hold the iwe in your hand and inspect it ,looks like it belongs on a go cart . The plastic piece that surrounds the teeth looks particularly flimsy. It is a manufactures point of failure part . I have not seen a replacement part for it ,really the whole system needs to dropped and redone. I engage that 4 wheel drive system like it is made of glass. The first vendor here that comes up with reasonable solution will be a folk hero. It is built to save the splines so warranty would go down the tubes.

Is this systemic across the fleet of 2012 13/14 , how many guys out there that DONT HAVE ANY ISSUES with theirs?

I would really like yo know if this is something that will eventually happen on ALL torsen front ends....if so I don't want the headache and will probably not purchase one until the new one comes out in 16.

I use 4wd up here in montana a lot in the winter and when off reading in the summer in my Superduty. That truck I can count on. I need to count on this Raptor TO WORK WHEN IT IS SUPPOSED TO!

If those owners who are in and out of 4wd a lot would chime in it would be appreciated!

I put on 4 raptor events this year and 2 last year. Within those 6 events I had 220 trucks attend. Let's assume 30% were 12s/13s so 66 trucks wheeling hard for a weekend. I can recall 1 IWE failure.

Not saying it isn't an issue but I think that statistic speaks volumes. Just like anything else on the Internet. You only hear about the people having problems.

My late build 2013 has popped since day 1 about 15% of the time it is in 4WD.

Mid-Perch and usually when the 4WD was engaged at idle and im climbing a sandy hill or somewhere where there is a lot of load on the system. It seems if I back off the throttle fully the IWE seats itself properly again and the popping noise goes away.

Happens with or without my tune also.

If I give the system a bit of time to engage at speed and tap the throttle on / off a few times I never have an issue *knock on wood*

Really annoying to have that happen in what is marketed as a bulletproof offroader

Thanks guys for the replies, keep them comming!

I know each truck has its issues and weak design points. My F350 has its idosycrocies as well when working the auto hubs in and out. But I TRUST it. I guess thats because weve been together since 1999!
