Have you tried using the -/+ gear select on the steering wheel to disable eco mode?It didn't seem related to eco mode before but it sure does now

Hi Guys. Just joined forum to address vibration this issue on my 2020 Ram 1500. I originally took it to dealer after a few thousand miles for slight vibration after backing off on the gas and then slowly reapplying the gas. Tech said he could feel it and he reprogrammed torque converter to latest firmware. That made it much worse. It didn't seem related to eco mode before but it sure does now. Took it back and I went with the tech for the test ride. He could feel it. I don't think he knew what to do about it so we took another similar truck off the lot and took for a ride. That truck also vibrated some but less and he said "There, this one does it too so its normal" and sent me on my way. I am very disappointed. Very embarrassing when I take someone for a ride and they question me about it. I'm afraid it will cause more damage the more it continues. I sure hope someone gets it fixed so the rest of us can get closure. This vibration has nothing to do with the wheel balance or wheels at all.
I can confirm you're suspicion...my Bridgestone tires are completely shot at 26K miles. Went to Costco yesterday and had new Michelins installed, that slight vibration at highway speeds is completely gone.The vibration felt in the eco mode is pretty much normal. On my truck, if you can get it in eco mode at 40 MPH, a vibration is pretty obvious. The constant vibration at highway speeds, whether in eco mode or not, is most likely the crappy Bridgestone tires.
Why are you so sure not tires or balance? Mine was way out of balance after 1000 miles and again at 2400 miles! 400 miles seems to be out of balance againHi Guys.

When these Dealers are “Roadforce balancing” as everyone is calling it on here they are messing up. I keep saying it but nobody seems to be listening. When they actually use the “Roadforce” function which the don’t really 99% of the time, they are looking for runout in the assembly. If it is over 20lbs which is approx 20 thousandths of an inch they attempt to index the tire to lower the number. That is great and is exactly what you should do. Here is where it falls apart for them. They use “Smartweight” when they actually balance and this mode leaves couple imbalance in the assembly. Couple imbalance is side to side vibration and something you will feel in your steering wheel and if bad enough will cause a steering wheel shimmy condition. This is not balancing your tires correctly at all but the Dealer techs and even Chrysler Engineers don’t know or will admit either. Even if they do know and turn it off those balancers only go down to .10 oz and those can stack up and still cause a problem. This whole issue comes from lack of understanding how to fix it and using a balancer with mediocre accuracy at best. Yes MDS, frame pods, driveshafts, differentials, etc all can cause vibrations. Without fixing the easiest thing (truly balancing tires) then they will continue to guess what it is.
This is a sensitivity issue with these trucks and yesterday’s balance does not cut it.

Are there specific questions or instructions you would recommended to the non balancing experts here when talking to a tire shop?
If I called a bunch, how would I know which ones actually know what they are doing and would do it correctly?

I would ask these questions...
1) Does your shop use low taper collet adapters on your balancer?
2) Do your technicians back cone with those collets 100% of the time?
3) Does your shop have and use pin plates 100% of the time?
4) Do your technicians perform a center check to ensure a properly mounted wheel to balancer?
5) Do your technicians perform a check spin after wheels weights are applied?
6) Do your technicians correct for residual imbalance? If so how? (On a Hunter machine turn Smartweight OFF)
7) Do your technicians check and correct for Static and Couple imbalance to under a .10oz? If so how?
8) Do your technicians ensure wheel fits tight to hub bore on car? If doesn't do you offer hub rings as a solution?
9) Do you road test vehicle after tire installation?
There are a few more questions like too little or too much tire lube when mounting. Too little tire lube and the tire may not seat correctly. Too much tire lube and the tire can move on the wheel and that will mess up your balance work. Are they re-using wheel weights, it's a horrible practice but some shops do. When have they calibrated their machine and how do they know if calibration was good. Are the cones/collets worn out or are they in good shape. Have the shop technicians been properly trained to operate equipment correctly and do they have the knowledge and skill set to correct imbalance. If so how do you know.
Here are links to the proper collets and pin plates I am referring to.

Also attached are some Bulletins that discuss proper collets and mounting. They don't address pin plates which is really stupid on their part. They do discuss RFV but unfortunately place more emphasis on this than the most common causes and corrections.
I know a lot of information... Hope this helps even one RAM owner!
Thanks
I’ve Owned several new vehicles and have never had to explain or do any of this for a smooth ride..why now?? I’ll tell ya why..because Chrysler has a issue that can’t be resolved..they should be having the dealers do this not the buyer..but I appreciate you going out your way to help fix their problem

Same with my 2020 Big Horn but seems to affect 1200rpm's up to 2000rpm's...give it a little gas take it up to 2400-3000prm's and it seems to go away. Some people are saying it's relevant to mph...but mine seems rpm's.I’m having a similar issue with my new rebel. Seems to be between 1600-1700 rpms causing a slight resonance in the cabin.
I titled my driver side mirror down and in to see the rear tire while driving and it visibly wobbles. I had my wife drive as I looked out the window and the passenger side spins straight. I plan to swap the rears left and right and see if the wobble follows the tire and not a crooked hub or brake rotorI had a problem with vibration years ago in another truck. The balance job was spot on. However, 3 of the 4 tires were "out of round." I figured cheap OEM tires were to blame. Finally got enough miles to justifiably replace them and it was a world difference and much smoother. I've heard also that wheels can be out of round too, which of course is also fixed by replacement.
Another thing that's highly possible is if you've had your truck "leveled" This can cause the drive shaft to become out of alignment on the CV joints and cause a vibration. I understand leveling looks cool, but mechanically it's a mistake. A few shops can help the CV alignment issue, but only a few.
