Well mine Jitters and stutters and and the nox when I'm going from 35 to 45 from 65 to 75. Usually only when I have the pedal push down so I have a nice level acceleration.
Check to see if your struts have been replaced, i know it sounds crazy. Measure the ride hight front VS Rear, if the front is higher that the rear, the struts/springs have been replaced and the aftermarket ones are 2" higher at ride height than factory. Just went through this with a 2007 Limited. Replaced the struts, developed a bad vibration under acceleration, just like a bad cv axle makes. Replaced both axles, with no change to the issue. Measured out the ride height and discovered the issue. Replaced the "AFTERMARKET" quick strut springs with the OEM ones, and the issue is resolved. I Sure as hell hope this helps someone, or alot of you guys.

It looks like I can buy all 4 mounts for around $125 so I may just go ahead and replace them all since they're original.
5 years on. but your issue is

You might take a look at the brake rotors to see if they are warped if a caliper is causing a pad to drag.
They said under load, not while braking. Random guessing does not help anyone. This is a common Chrysler problem.

When we can't experience the problem first-hand, everything is a guess. On the bright side the haziness means thread contributors may be considering things the OP hadn't.

And yes, bad rotors can still give a shaking sensation even when not braking.

Bad rotors are not unique to any make. In the interest of decreasing weight many brands are making the rotors thinner. It's getting to where turning them is no longer feasible.

This thread is kinda dead, or at least it should be. OP hasn't been on the site in 5 years so I hope the problem has been solved by now. It's nice when people report back but it doesn't always happen.

Something similar happened to me, I mentioned it in general discussion awhile back. Same day it happened I think. Turned off the state highway onto a side road heading to a friend's place, stepped on the accelerator to rev up like usual, and as it was winding up, the whole thing started shaking, not really wanting to accelerate much. Only under power too. Scared the crap out of me, as I didn't know if it was the engine belt, the CVT, bad motor mount, whatever. Even tried putting it in neutral then back to drive, and that didn't help. Wasn't in a place I could pull over either, road was kinda narrow. So I nursed it the few remaining miles to my friend's place, pulled in, parked, and shut it down. Engine belt was good, and it sounded fine when I turned it on a few minutes later and revved it. Decided to risk driving it again, so I got back on the road and it worked fine, no problem whatsoever. Like it never had that problem to begin with. My guess is the CVT belt started slipping or shaking somehow, and needed to be completely stopped and disengaged to start working again.

Daughter has a 2016 pat 2.4 4/4 she uses for mail service and was giving a bad vibration at around 30 and would smooth out some higher speed, 3 of the wheels had had the wheel bearing replace and her mech said the last one was good he finally gave up on it he thought it was the rear drive unit going bad,,,,boo hoo $$$ there, finally took it to the dealership and they came back and said the last rear wheel bearing was bad, they replaced it and vib and noise was gone, but it didnt sound anything like a normal wheel bearing gone bad
