I have noticed while driving around a curve that it leans outwards, like I am about to lose control or tip it over. It is very noticeable at 70-80 mph and gets down right scary.

When passing people up it gets really bad cause the Truck seems to tilt one way and I always jerk back to adjust. I feel that it may cause a wreck in the future.
My wife says that it feels like the rear tires are slipping, but I get a whole different feeling.

Just wondering if anybody else notices this or if there is a fix for it other than changing out the whole suspension.

At that speed, by default, the Rebel lowers itself to Areo mode, changing geometry.
Solution: Disable Areo mode in the Uconnect menu under suspension.

Disable Aero mode, truck is better in normal on highway. I find aero mode to be useless, except for modding links.

Does your steering wheel come back to center on it's own? Mine currently stops at about 15 degrees (different thread). The dealer is still trying to figure it out. They did an alignment, which helped, but the problem is back in full-force after about 2 weeks.

Asking, because I too get this sensation a times, and I sort of feel it's due to that and me having to over-correct the wheel after turns or changing lanes Makes me a little nervous in traffic.

I also get a fish-tailing feeling during acceleration, too. I think it's all related, because the rear end pushes (obviously) and there's not much holding the front tires straight, besides the driver.

Same response I provided over in ramrebel.org - basically you are just driving too fast:
I'm old enough that I've retired twice, the first time from the military. I've never, ever rolled a truck. Gotta agree with the other guys here, if you're tipping and swaying around, you're trying to turn too tightly for your speed. If you're tilting the truck when passing people you're changing lanes way way way too quickly. I don't want to be near you on the road when you're doing that, don't even want to be a witness from a long way away.

You didn't post the "70-80 mph" part in the other forum. But raindog over there answered pretty well with his comment, too:
I have driven dozens of different light trucks over more than 35 years, and my Rebel handles at least as well as the best of them. These are trucks, not sports cars, so if you feel your truck is about to "tip over" when cornering, you are driving far too fast. Slow down.

And the adjustment from normal to aero mode is not enough to cause this. Unless you've done some extreme mods to the truck suspension.

If excessive speed is not the root cause of this supposed instability, then there has to be some seriously broken suspension or drive train components to blame. Have it towed to a dealer for a diagnosis and get back to us with the results.

Mine does this as well guys. If were talking about the same thing, its almost like a shimmy and the truck feels like its slipping and banks in a way. Slower speed does make a difference in my case but I think this has something to do with our brakes or air suspension. I believe it could be part of the brake system. When your truck is cornering and it senses extra movement from the tires on the outside of the curve and I think the system applys slight brake pressure to correct. If its not that then its our air bags correcting for the roll in the body. I haven't tried this yet (and I will soon) but try deactivativating the traction control by pushing the button on the consol below your nav. Has anyone tried that? Let me know if it makes a difference and I'll do the same

Are you driving with it in 4wd high lock? This sort of feeling does happen somewhat with any vehicle in locked 4wd. As the turn gets tighter, the outer wheels are covering more ground than the inner wheels on the turn, yet all are trying to cover exactly the same ground. So one tire in the front pair and one in the rear pair will always be slipping/skipping in turns. Not good on pavement - wears your tires down VERY fast. Turns 60,000 mile tires into 15,000 miles or so.

And this doesn't sound related at all to the other problem, tipping over and swaying in turns and lane changes.

Interesting, but I think if the stability control is activating, you are driving too fast for the conditions. The system is attempting to prevent a total loss of control by applying selective braking to individual wheels. It can only do so much though, it is still up to the driver to understand the limitations.
I have also read that it cannot really be turned completely off, and still operates to some degree despite the "off" setting. I have not confirmed this for myself, and don't intend to drive in a reckless fashion to find out how this could impact cornering performance. However, it is my understanding that it is automatically turned off (at least as much as possible) when you engage 4WD Low. Turning it off can be an advantage in mud or on snow when you want the tires to spin to maintain momentum, but I am not sure why you would want to disable it for normal driving.


I would also be surprised to find the air suspension is at fault, as, in theory at least, it would attempt to raise the side that was leaning in. One would think this would counteract the body roll for flatter cornering, but with a heavy truck that has a high center of gravity I am not sure how effective it could be.


In any case, if one is observing sane speeds near the posted limits and finds the handling squirrelly, take it in to your dealer for a check. For what it is worth, my truck doesn't exhibit the behavior described, so I feel this is not normal.

Maybe you just need someone to ride along with you that knows trucks really well and has been driving them for a couple of decades. Be sure to issue helmets. :)

I forgot to add that I have not modified my suspension in any way, nor have I changed the tires, wheels, wheel offset, or alignment settings. I have no issues with the handling...................go figure!

I can attest to the traction control part of this. Had my truck in some thick mud this past hunting season and the traction control did its job braking the truck almost to a stop (not good in mud obviously). Take it off and its fine. In four high same thing and four low it did not engage.

I gave this some more thought, are you running wheel spacers or have otherwise changed the wheel offset by any chance? This may change the steering geometry enough to cause instability on hard cornering, especially if the pavement is a bit rough.

Sorry for my delayed response. I noticed a big difference going to normal mode instead of aero mode. However as of recent I started feeling it again. Going to take it in to be looked at
