2019 1500 classic

[Lukewoj]

I have a 2019 1500 classic and it shakes around 78mph and up it has done it ever since it drove away from the dealer anyone know of anything it could be?

Check the balance on the tires, are they the original tires and rims?

 

[Lukewoj]

Yes. It's been doing it ever since i got it

It's the same even after rotating tires over the past ~2yrs?

If it is a tire out of balance you'll probably still feel the shake, but it should be different depending on which corner.

I haven't rotated them yet doing it next week but the center console is where most of the shake comes from but it feels like it's the whole truck

I would inspect the driveshaft and see if the balance weights are still intact and make sure the u-joints are properly installed. Make sure the driveshaft does not have any dings or dents in it either.

Does the truck shake and vibrate at any other speeds?

Have you attempted to isolate the vibration to a certain gear in the trans while driving? Does it still vibrate a varying engine RPM? Drive regular until you feel it vibrate and then downshift to 7th and then 6th to see if the vibration changes or is eliminated.

Try bringing the engine RPM up against the brakes while in gear to see if you can duplicate the vibration.

These are all shots in the dark without seeing the truck in front of me.

Have you taken it in to have it looked at? This would be something that's covered by warranty. You've been living with this for 2 years, or did you recently buy it?

 

[Lukewoj]

I got it last summer and it's going to get looked at next week

 

[Daw14]

Probably tires need balanced.

 

[mikeru]

Not real forthcoming with the details are ya Luke? LOL I blame myself for not asking all of the questions up front. Last question I have is did you buy this truck new, or was it used?

 

[Lukewoj]

I bought it new and sorry about that lol it's hard to explain it

 

[mikeru]

No worries LOL. You might consider putting your vehicle information in your sig so you won't have to answer as many questions any time you ask for help with something.

While it's possible that your problem is as simple as a wheel out of balance, since you bought the truck new I would suspect the problem is something else. Factory balance is normally better than the standard spin-balance you'll get from a tire store. And you said it's been happening since the day you drove it off the lot. I'm thinking you should have turned right around and had them take a look at it when you bought it, but that's history now. I'd take it in at the first chance you have and let them know you've had this problem since you took delivery. It is definitely something that your warranty should cover.

Wheel out of balance, probably a front one threw a weight. Almost all speed-related shakes are caused by this. Cheap fix.
