Your truck looks amazing with the combo you picked!

My current 2015 GMC hardly has any vibration and would almost say its 98% the tires causing the issue in my case.. but I know what it's like, my last truck (2014 Silverado) had a HORRIBLE shake/vibration above 65 mpg like others.

Interesting article but I wish it had more on the trucks vibration than a blanket over both SUV and trucks.

I think hub centric is the better choice when buying wheels. If you can get hub centric rings to use with your wheels, I'd suggest doing it. Just make sure you use some emery cloth on the hub and make it nice and clean before to eliminate any possible issues.

Some.. but not everyone. Don't tell me your 2016 is doing it already?

Front runner - Your one of the lucky ones. My last silverado shook so bad at 75 mpg that it could nearly shake a bottle out of the center console. At times, I felt it was actually unsafe to drive it was that bad. Some trucks are obviously worse than others. When I first purchased the truck, it was smooth as butter going down the road but as mileage was added, the shake got worse. The dealership balanced the tires more than once, I took it to a tire shop and determined 1 tire was bad.. Smoking gun I suppose or so I thought. I had the tire replaced and all seemed better at first, but was obviously still not 100% smooth. With my truck I would observe smooth the truck riding smooth, then start into a violent shake, then smooth out, and repeat. Almost like a harmonic issue. I rotated the tires and still had the vibration. Always from the rear no matter what position the tires were in. I switched tires with another truck and the vibration was still there. For that truck I believe the rear gear set or pinion gear was the issue. I never got it resolved and like others here, traded. My excuse was I wanted a crew cab to justify the trade. My new truck is smooth, but not as butter all the time which is disappointing. My new truck is more than tolerable and is no where near what the last truck was. More annoying than anything really because I'm so sensitive to the issue now. My wife or passengers don't even feel it anymore. I actually believe this time it is the tires. I'll run them till I need new ones and will replace them and hope for the best. Some trucks have a serious vibration and it's not an easy fix. I would think that GM will see/find a real solution soon since there's more than 2 years data of dealerships diagnosing it. I do believe that alot of these trucks had bad tires on them and that's all they needed to fix the issue but others have a pretty violent shake that isn't from the tires. That's the real problem here.

FYI, they can't void the entire trucks warranty due to the lift. I've owned a lifted truck and they can only void the parts replaced. Don't let them tell you your entire warranty is void. Unless they can prove the lift is causing the issue, there's no reason they can't diagnose it. If they can't find the issue, well they can't find the issue. Soosick13, it sounds to me you have a BAD dealership. Heck GM sells the Rocky Ridge and gives a full warranty on that truck. Thats a 6" lift with 35" tires. When I had my lifted 03, the dealership was very good with things being modified. As long as the problem didn't pertain to the lift, everything was fixed.

I just printed it out just in case.. haha

What style wheels?

Thanks. I'm happy!

The Goodyear ls2s suck all the way around. I have them and hate them. Can't wait for them to burn off.

Its really disturbing GM isn't finding a fix.

Robvas - Those look sweet!

Thanks, I think they look awesome on the truck!

2011 6.2 with NHT was 9.5". Are you getting confused with year. Maybe the new ones have 9.76" and pre-2014 has 9.5"?

The big difference between the 2 is the torque. Not so much in HP. Also does the 2004 motor come with drive by wire? Make sure it doesnt. Should be an easy swap

Are the wheels hub centric ? If not that could be your problem
