Silverado 2017 LTZ shake in front end

Just wondering if anyone on here has had this issue with their recent Silverado?
This Truck is a 2017, LTZ, 6.2 Liter, 8 speed, 19,000 Miles. Bought in October, 2016 so vehicle is 25 months old.
We just came down from Canada without the Trailer, 2100 Miles (3380Kms) and experienced a shake in the steering wheel at various speeds usually at certain specific speeds like 56 Mph and under slight load like on a hill or just accelerating, a few more MPH and it stops. Now that we are here in Florida I find it does this at certain lower speeds like 40 MPH raise it to 45 and it stops.

It appears to be in the front end as I can feel it through the steering wheel. I had to before leaving Canada get a new Goodyear Tire due to a nail in the wall of the existing front right wheel, the tires were rotated and this new tire was placed on the left rear of the vehicle. Not much wear on any of the existing tires so all the existing tires depth is close to the new tire.
The tires are Goodyear Eagle LS-2 275/55R20

I was curious if anyone had this experience, I am going to get an appointment with the local Chevy dealer, I am thinking he might balance the tires and if that does not stop it maybe it's in the running mechanism. There is some discussion on the Tranny in these vehicles and I experience it also like aggressive shifting and noisy thuds (sometimes, not all the times) I have had several dealers look into this with the no trouble found response.
Thinking it could be tires, maybe broken hidden belts, unbalanced tires, or a problem in the running gear, Tranny, etc.
Appreciate any experience others may have had in regards to this issue, thanks....Ernie

    Just to close out this thread...
    Went to Alan "Js" Chevrolet dealer here in Sebring, Fl, they did work as per PIP5337E took all day,said to put on 200 miles and this will give three changes to the fluid, I drove to Orlando from here 100 up and same back,rumble strips replicating is now gone.
    Alan Js were great as was Big "T" Tire in Avon Park,I asked Big T Tire for 4 wheel balancing before going to Chev Dealer, the Tech took the vehicle for a drive said "no need for tire balance, go to Chev dealer, trouble is not in tires, I don't want to take your money"
    So in this age its hard to get great service especially in two business but I did!
    Thanks everyone that offered help, this thread might help others as others helped me.....pass it on....

    Here's another link to this issue, hope it opens for anyone interested, it does appear as if in the trucks the problem is with the 6.2 liter Engines.

    My truck is the 1500 LTZ, 6.2 Liter, 8 speed, 4WD

    Follow up on Silverado 2017 LTZ shake in front end

    1.) Went to Big "T" Tire in Avon Park this morning (They are the Tire Specialists in this area, used them before and they seem upfront, great customer service), got tires checked out.
    2.) Result...no problem what so ever with the tires, the Tech took it out for a drive and said its not in the Tires definitely.
    3.) So I called Alan J's the big Chevrolet dealer here in Sebring, as soon as I mentioned the shake, the fact Big "T" Tire checked it out they made an all day appointment for the truck for 8AM (Sharp) next Tuesday, December 4th with their Transmission Technician, given the Transmission Tech's name also, and drive back home here as its apparently an all day job.

    So as far as I can tell it looks like a change of (I Think) the Torque Convertor.
    And so far dealing with Big "T" Tire and Alan Jay's I give them great support.....might change but hope Alan'Js come thru....I have dealt with them before and was always pleased, so here's hoping.

    BTW I have to go 100 miles this weekend to Orlando Airport to pick up my daughter, told the Alan J's rep I didn't know if it was safe or not, he said "Not to worry, it will get you there and back"

    BTW, More importantly, I did find a GM Service Bulletin on this shake it is #PIP5337C and pretty well describes the issue but does put different specs on what it acts like, read it through if interested.
    Link here #PIP5337C

    Anyway will follow up here as this issue develops.... Ernie

    I have had the same type of problem and it was a tire developing a blister on the inside. The tire looked fine when inflated on the truck but if you let the air out you could see the tread had developed a concave appearance. It had a 2-3 inch wide blister that ran almost 1/4th of the way around the inside circumference. Easy to check for, jack up the front end, let the air out of the tires and see if the tread stays flat or changes shape on one tire versus the other.

    Well, April is a long ways away....lol, you should be fine!
    Just stick the front tires on the back and see if the shake goes away or moves. First thing, that is easy, free (unless you don't change tires) and will definitively show as a bad tire or rule out the tires.

    Since this (presumably) just started its not as likely you have the Chevy shake.

    FWiw, typically, small vibrations that are only apparent at a particular speed or 2 are tire related. Drivetrain type issues typically present at multiple speeds and increase in frequency or amplitude as speed increases.

    With the tires rotated could one of the rears have been a little unbalanced and just not noticeable because it was on the rear? Now it's on the front and it's an issue?


    Thanks for the reply, No, don't think that is the problem as I have rotated the tires three times since purchase.... but like you say maybe the rear tire developed an issue and now on the front is having tremors and shaking .....good answer though.
    Today I called Big "T" Tire in Avon Park, FL, bit north of us, closed but open Monday so will get appointment next week, will let you know the results of the issue.
    Geeze I hope someone can fix before going home in April, I don't like the 2100 mile drive with this issue on an almost new Vehicle. Maybe its the tires, not in love with them, I always had Michelin LTX Tires on our previous Chevy Diesel which BTW with Michelin and an ALLISON TRANNY NEVER had a hitch.
    Thanks for all the replies and your help, welcome any more suggestions....Ernie
