Vibration at Interstate Speeds

Hey guys, what’s the chance it’s improperly balanced driveshafts, like a previous poster said. Maybe the driveshafts themselves are the problem, and OEM isn’t the right answer?

I'm 90% sure it is the front axles.

I have a 2024 wt and I don’t have the vibration. It’s 4x4, 5.3, 10-speed.

it does have other issues though.

It's entirely possible you're still dealing with a tire issue. I went through this a few years back with an F150. Smooth as glass on factory tires, then shook like you describe at 70 after getting them replaced with Goodyears. Balanced, re-balanced on the road force machine and still did it. Warrantied the set and those shook. Warrantied again and switched to Coopers and those shook again! Had those tires road-force balanced at another shop and that finally fixed it. It was implied the previous shop had a tire balancing machine that was out of calibration.

I had this issue with my 25' SLT. I took it in, and they rebalanced it. It seemed to go away, and I do have the range DFM disabler. I will monitor and report back if it returns.

Turns out that my issue was the bfg ko3 tires I had put on it. Thankfully the tire dealer replaced them with my choice of tire since I had reported the issue to them twice after the purchase back in May.

I spoke too soon, went on a short trip today and vibration is still there, around 1400 to 1500 rpms. Seems to only be noticeable after driving 10 miles or so, then it starts.

I've been back to the tire shop twice for balancing. They even had a tech come out and calibrate their tire balancer. Still had a vibration. Took it in for the road force balancing, and the vibration comes and goes, but is still noticable. Unfortunately, our roads here in the winter aren't very smooth now, so the vibration is usually overwhelmed by the rough roads.

As someone who's done a lot of troubleshooting on this, including installing brand new OEM 20" wheels in place of the stock 22" wheels on my 22 refresh Denali, as well as have spoken to lemon law attorneys, I've noticed that I don't feel it when there's a strong cross wind. Could it be wind turbulence we're feeling? I ask this partly because it only happens at moderate to moderate-high freeway speed range , I don't feel it when in a strong cross wind, and I have never heard of someone with an AT4 or Trail Boss complaining about this.

Just wondering if anyone has had resolution of the vibration issue. My 2024 2500 AT4 was vibrating on the way home from the Out of Town dealer. Balancing, One new tire, Set of New tires, Never really went away, Now at 52K Switched to Michelins from the Goodyears and new brakes all around. Still have a vibration between 60 and 70 which is where it all started. Any ideas would be appreciated.

There goes my theory that it might be a wind vibration, given you have the 2" lift, and I thought it might be wind going under the "normal" height models.

That said, I have noticed that if I put my fingers in the area between the door and body while driving, I can feel the slop between the two pieces as they move around inependently of each other. Not enough to let wind in, but I can't help but wonder if all the body parts have that much tolerance, could the vibration be from these parts shifting around? My son's and daughter's Hondas don't have this much play, and neither does my wife's Mazda CX5. I also don't recall my Suburban being like that either, and it didn't vibrate like this truck. It is entirely possible that all the trucks have a wider tolerance and thereby vibrate because they simply didn't make them as tight as their other vehicles. I've been trying to find someone with a Tundra that I can ride in and see how they are but I would venture to guess they are tight and smooth.

Did anyone find a resolution to this problem? I have my 2023 Silverado 3.0 in the shop now for this problem. They have checked, driveshaft balance, cab and engine mounts, axle run out, torque converter lock up and pinion angles. I’m really starting to believe it has something to do with the ARC as most of the people I see commenting have that on their trucks. Like most I have dealt with the wheels and tire solution to not fix. My OEM wheels had the shake and 2 set of aftermarket wheels and 3 set of tires later I still have the shake. All my road force numbers are great. The dealership placed my wheels and tires on another truck with ARC and that truck would shake. I’m going to ask them now to place my wheels and tires on a truck without it and see if it shakes. They also placed the other trucks oem wheels on my truck and my shake is still there. Any help would be appreciated. GM field tech believes it’s my level kit but I know it is not that.

After changing tires, I ended up having a nasty vibration… But even before, I did notice a vibration at about 70 mph. What ultimately fixed it was a set of good quality tires, paired with a different set of rear shackles to raise the rear end… Ultimately changing the pinion angle. That may be where the problem lies with these trucks… Because I've noticed that a lot of of them don't have shims between the rear axle and the leaf springs.
