Are the IWE's up front on the new trucks ran off vacuum still or has the style changed? More reliable?

 

They are electric now. Some say that they are more reliable. Others have had issues. I am at 61,000 miles on my 2021 and have used 4x4 regularly at the boat ramps and out on the trail. I haven't had any issues or noises. It's nice not to have to think about whether I have the front hubs locked or unlocked like I did in my 2001 Super Duty.

 

I have. 2023 with 1000 Miles and my eiwe are grinding just like my 2019. Only happens at 32 or colder though. Pain in the butt. Should have went with a tundra.
