After the 3rd set of tires and 70k miles, the vibration has been almost nonexistent at times and horrendous at other times, despite having the tires balanced at least every 10k miles.

I'm going to check the run-out of my tires, wheels, and axles before i start raising hell at the dealership.

 

What truck do you have the vibration on??? Almost sounds like resonance bounce!!!

 

Ok i watched the video, its the 14, i assume. theres a whole thread of people complaining about that somewhere, think it either gmfs or silveradosierra...

 

Rear end. Take to dealer.

 

Mine has vibrated at certain speeds from day one and 2" shackles exaggerated the vibrations. After the flip kit it vibrates slightly as it did at stock height. After 1" shackles were added to the flip it vibrated same as it did with only 2" shackles in rear. Took shackles out for 7" flip and back to "normal"

It's only slight and I'm not too worried about it though

 

My brother has a new '15 RCSB blackout that did this. I suggested he disable the cylinder deactivation. Once that was done the truck is smooth as glass. GM's AFM isn't perfect.

 

The AFM has nothing to do with my issue.

 

my speakers don't work but my vibration is very subtle when I am trailering something. Mine feels like it comes from the transmission tunnel though. Stock 2015 Double cab with the 5.3

For me it's not concerning, but it is unnerving when a dealer can't step up and fix an issue, especially if it is something mechanical.

 

Do you know anyone with a set of stock wheels and tires you could swap on for diagnostics just to start there if you aren't on stockers. Depending on dealer if you've done suspension and or wheel and tire changes they tend to not be very helpful. The closest to stock you can get it yields your best chance of a solution from both the dealer and field service guys should they need to get involved.

Chevy or GMC our shop has dealt with atzenhoffer for over 20 years the guys in their truck shop are good.

 

mine has done it since day one.. three different sets of wheels and tires.
