^ what he said. It's not a visual thing, you just feel it. and it's quick, but present nonetheless.
If you have AD1, and the straight shafts, and you *think* you feel a wobble....then ya gots the wobble.

anyone know if it's any kind of danger or just a quirky annoyance. I feel it just slightly but it's not really a bother if it's not a safety concern

No danger we know of. I do wonder how such a frequent vibration could effect the drivetrain in the long term ; things getting loose, out of alignment, etc... it's hard to say.

Try turning off Hill Start Assist (in UConnect) or driving around in ERS 7th for a bit. Doing either has reduced the wobble to almost nil for many here. It did for me, but being 100% wobble-free is so much better...

followup question(s) is the wobble due to bent axles shafts? if so, then wouldn't we feel some wobble at all speeds like at highway speeds?

why would hill start assist have anything to do with it? sorry, coming late to the game

Yeah we've covered this extensively in many threads, but I realize the info may not be easy to find, so I'll go quickly :

The wobble is not the result of bent axle shafts, or bent anything. We actually don't know the exact cause, because FCA hasn't revealed it, but we've pretty much narrowed it down to a few possibilities : because stepped shafts with narrower inside CV joints mitigate the shimmy, it's pretty obvious this *fix* changes the forces (rotational) in a way to prevent the oscillation from occuring.
And we have read that FCA are redesigning the front suspension and steering for 2017, so we suspect a design error is causing the wobble, or incorrect fit/tolerances somewhere in the transaxle. Since only a minority of AD1s have the wobble, it is likely a little of both : poor design sets the table and then if something is misaligned ever so slightly, the Jeep will shake.
It shakes within a very small speed window because of a frequency thing : the right forces at the right rotation speed under the right load (throttle).

What do Hill Start Assist and ERS have to do with the wobble ? If I could answer that... Basically, we have no idea and no one at FCA is talking.

Same for wobbly FWDs.
FCA will eventually act if enough people complain. If they claim to have fixed the wobble on 2016s while retaining straight shafts, ask them to appoint a trained tech to assess your vehicule's wobble.


for what it's worth, i tried that -- contacting FCA directly, and they essentially told me to take it to a dealer to have them assess the situation. FCA did seem to stay in contact with the dealer, so i'll give them that, but if your dealer (like mine) refuses to admit there's a problem, or "cant reproduce the issue," FCA drops the case but keeps a record of it in their system, which they can refer to later if it's ever reopened.


that's the status of mine (FWD 2015) right now. i'm basically keeping a daily log of whenever i feel the wobble as best i can, and i might attempt to recreate it with the dealer again in the future, but i got burnt out trying to explain things and taking off work to bring the jeep to them.


i do 100% agree that folks should be calling FCA, though. the more voices complaining, the more difficult the problem is for them to ignore (or kick the can, or whatever).

@osirisdean : oh man, sorry to hear that... I do wonder whether there isn't one department over at FCA that *might care* a little more than the front line (so to speak) ; but as you've experienced, they are clearly screening the proverbial calls before letting anybody go up the technical support chain. That's a little sad, but understandable.

I also understand you being tired of all this and needing to take a break. We can only hope they *get it* sooner than later...

Hi there,

Sorry to hear you've got that shaking thing going on with your 2016...

Just curious : are you considering talking to your service person at the dealership about this ? Just mention you know of a TSB for this wobble (don't go any further, don't mention model year...) and let them dance a little
FCA needs to get calls from dealerships about this, 2016 AD1s and all the FWD wobblers as well.

Probably wait until January before I talk with them. Too much going on with the holidays right now and there are a few mods I am considering. Get it all taken care of in one stop.
