New vibration

[Berky]

2022 ST. Just over 60k miles

I have a new deceleration vibration occurring. It’s felt throughout the entire cabin. I let off the gas coming to a stop and a wave of vibration happens. I’m not sure if it’s drivetrain or exhaust. When I shift into neutral it goes away. I just had a new rear driveshaft installed under warranty to remedy a pulse vibration while driving 45-55 mph. This is something else. I’m hoping for some insight before I bring this problem to the dealer once again. It seems like exhaust, but I’m not sure. It started when the weather got cold in Wisconsin, but not sure if that’s related to the issue. It certainly doesn’t seem normal.
Anyone have an issue like this?
Thanks

Ford and these shakes (had it in my edge ST in the 40-50mph and my F150).

@Berky Some info in this thread. My guess it's the poorly designed stock exhaust.

Thanks for the input! I’ll read through and determine what aligns with my issue. It really feels like exhaust, but could be any random drivetrain issue as well. I’ve put 3k on this used explorer and can’t believe how wacky this transmission is. Dealer says it’s normal. If this is normal shame on Ford. It Shifts great, then does something strange. Sport mode downshifts are random and abrupt in the lower gears. A new rear driveshaft helped with some of the shakes. Now I have this vibration that’s simulates the engine dying when rolling to a stop. Strange. I’ll take a look at the flex pipes. Possibly get it in for the 60k maintenance and let the dealer dig in. I’ll update as well
