I'm not a mechanic, computer guy by trade so I don't really know cars that well, but I need to know if my suspension is going. Here are the symptoms. In anything but Track mode the car feels exceptionally floaty now, it didn't feel that way last year when I got it new. Any type of lane changes over grooved roads or doing any spirited driving and going around corners and hitting any kind of bumps the car is all over the place. It only has 11K Km, on it, so it hasn't been driven much. My rear tires are almost gone, but would this contribute to that feeling? Are there any tests I can perform or telltale signs to look at? Thanks in advance.

Have you checked your tire air pressure?

Get a four wheel alignment first.

My charger feels the same way I have 7000 miles and it has been this way for a long time. At higher speeds the front does seem to float around I have had it checked and reassured it is nothing. In track mode everything tightens up

I have found the same "feeling" after installing the KW lowering springs and new wheels and tires (stock size on the front, 305's in the back). I'm thinking the alignment is off too. Time to make an appointment at the alignment shop I guess

I'm in agreements with a lot of numbers here, definitely check air pressure, it won't hurt to check the alignment, tire God is an exceptional contributor on the site for everything and anything about tires

Tire pressure is right around 30-32 psi. But could it be an alignment, it does pull a little to the right would that contribute to it feeling floaty?

Do you drive in track mode a lot? I'm only asking because going from track to street does feel floaty (the difference).

No, no other updates, I haven't had Dodge look at the suspension yet, I had a hole in my Rad so had to get that fixed first. Now its on to the suspension. It still feels the same way, but I may wait until I get new tires as my rears are bald at this point.

Doug, do you want me to take your car out for a rip and let you know if it's just in your mind? ;)

My 2018 does exactly the same thing. It’s like something is loose. At 50-60 mph it feels like it wants to skate sideways, especially in a curve with bumps.

The behavior you describe can be due to shock absorber wear. But it can just be normal, well normal if the shock or rear suspension is not too good.

Years ago a car I owned manifested this behavior that was particularly noticeable on a very sharp turn that from the traffic developed a nice set of ripples. The car was pretty new. I drove the car to over 150K miles and except for that behavior on that turn and a few times I encountered similar turns elsewhere, did not manifest any other sighs fo shock or suspension wear.

It just so happened that car had a solid rear axle. The last car I owned that had a solid rear axle.

Years later when I moved back to the area I drove another car of mine over the that road and around that turn. Even though the road had been resurfaced traffic still sooner or later (mostly sooner) generated the ripples in the pavement. The car felt fine. This even though the car had considerably more miles on it than the first car did. It also had a much more sophisticated rear suspension. I drove this car to 317K miles and it was just starting to show signs the suspension (shocks mostly) were getting close to needing replacement.

I was able to use this turn to "test" a number of cars over the years and they were pretty much ok. I don't recall any car behaving quite like the 1st car.

My usual advice is if the shocks are not showing any leak sign, if the suspension joints are all "tight" -- I watched techs check these: the pull and tug on the various suspension hardware looking for any signs excesive play -- if the car does not manifest porpoising behavior, alignment remains good and tire wear acceptable with no wear that can be a sign of suspension/shock problems the suspension/shocks are ok. They may behave like you describe but it is not because they are worn or the suspension is worn it is because the shocks or suspension is not very good.
