Yes I've had new rotors put on since it started. Still there.

We use discount all the time, have one close to us. I'll have to ask about the road force balance. I thought it was just a standard balance.

Miketk101 that's a good thought. Only been traditional balance. Only have one shop around that does forced road balance. May give that a shot.

Sorry I wasn't clear. This began at about 35-40k miles. Still had the first set of tires on it. It was under warrenty and the service manager said it was the tires. Same issue with 2md set. No one has found anything. Out of round axels sounds like a nightmare.

Hey so this is my first post. Have a 2015 Sierra with the 5.3 L V8. Ran very smooth when I first got in 2016. It developed a shake at 73 MPH. Took it in to be looked at and the service manager told me it was a tire, I must have damages it on a curb (which was possible). Once I got new tires it continued, no one has been able to figure out why. Not sure anyone has ever checked the drive shaft or anything. Currently I've got 150K miles on it and unfortunately I'm kind of used to it but would love to get rid of it if I could. Crazy thing is that it seems to be worse at some points and I can't tell why. I've had wheels rotated and balanced even with this new set several times. Could I have bent a rim? I would have thought balancing would show that. Thanks for any input
