2023 Tremor IWE?

[Big Rave]

Hey all.
Can anyone confirm if there are IWE's on the 2023 model with the standard front differential and/or with the Torsen differential?

Thanks,

If it's four wheel drive. 21'+ are now electric, easy to look and see them.

Yes, I know they are electric on the 21's....I have one, and have replaced 3 of them in 60,000 miles. I've read that they started to delete them on some 22 models so I'm trying to confirm if they are on the 2023 Tremor before I order one, because I prefer if they are deleted.
If someone has one sitting in the driveway, can you please let me know if yours has them or not.

My 2023 has IWE and it's vacuum btw, not electric.

They went back to vacuum for 2023? I wonder if it's a parts shortage thing.

So are they permanently locked in? My 22' has them still, but thats interesting if they got rid of them. Pretty problematic in the past.

I'll double check again once I get the truck back... but I'll 99% sure its vacuum.

Thanks for checking. I does seem odd that they would go back to vacuum actuated.

Yes, if no IWE the axles are locked and always turning. I think the IWE's are mainly to help reduce fuel economy....but it would minimal. I'm okay with that, one less thing to go wrong...especially since I haven't had much luck with them on my 21 Lariat and now the warranty is done.

They have always been a problem, and now the EIWE’s are acting up. I read a few other forum threads as I have not seen any without it. Sure enough some are not getting them, No one knows if it’s related to trim level, TOD transfer case or what. I agree, I would be fine without them, but a lot of people especially on the Tremor have high CV angles with their levels. They could help with premature CV and Boot wear.

There is a vent hose that comes off of them, so they can look vac. I'd bet* a 72 oz of beer that's what you're seeing.

Only on the normal TOD trucks.

While there are a few theories, mine is that it's a fallback strategy in case the T-Case can't shift out of 4H on the ESOF or Hi-lock, so you can drive on the street.

On the TOD the clutch pack fails to disengage, or worst case without power it would allow for slippage.

They don't seem to be needed for any engagement process, as there's at least one person who swapped the Hi-Lock into a 22 Lariat sans-IWE. He had to plug the IWEs in to the truck to get the TCCM to be happy, but is running with the permanent hubs and no odd behavior.
