2023 Tundra shaking at high speeds

Hello
I have a 2023 tundra with 24,000 miles. The other day will driving on the highway the truck started to shake bad... looking at the speedometer almost messed with my eyes.

It's at the dealer now for 5 days. Can't get an answer on what they found. Feel like they are playing a game or something... like they found something and don't want to tell me. Any thoughts on maybe this is the start of an engine failure.

Thanks!

 

Build date? Just threw a wheel weight?

 

Describe the shaking.

Was it constant? While braking? While accelerating? Did the shake change based on RPM or speed?

 

Not sure on RPM... but for sure on speed. Anything above 50 mph. Constant shake. Not when braking or while accelerating.

 

Did you feel it in steering wheel at beginning? @Goody

 

Nope

 

So, just to be clear, the shaking was constant above 50 mph, but would go away while braking and accelerating above 50?

 

Driveshaft maybe?

 

Try a tire shop. Factory tires are garbage. One might of separated or it threw a weight like KANABORES said. Dealers are NOT tire shops

 

Would be worth checking wheels and tires out first. I work for commercial business and have for 24 years. We have people come to us often that have tire or wheel issues that other shops don't know what to look for when it comes to wheels and tires. Because that do not have years of experience of dealing with wheels and tires.
