Regarding the shake on 2023 tundra during acceleration

After extensive diagnosis - Toyota engineers and the dealer have determined that the drive shaft is defective and is out of balance.
As of 01/30/2024 they are on back order. I hope this post helps everyone who has this issue. I have suggested to them the following: loose engine mounts ; faulty torque converter; faulty hybrid motor; bad transmission and faulty drive shaft. I was right on the money on the drive shaft. Also - this is a known issue with the drive shaft manufactured from 2022 all the way up to 2024 on some models.

 

Does this present like a lugging sensation? Like when you drive a manual car, and you decrease vehicle speed, should downshift but don’t and try to accelerate?

 

This what I am feelin in my 2023 Tundra , Dealership can’t replicate but they took out for very small test drive ,

is there anyway I can confirm this myself or prove this or is there more resources to confirm this post that the Dealership & the engineer found this !?

 

Mine has the same shake, more noticeable when towing when I get to 55-60mph and above. Dealership wants me to drag my trailer over to them (1.5hr one way) so they can feel it, as they don’t feel in a quick test drive, no trailer. They tell me they have no way to check driveshaft balance and if they can’t replicate it….can’t attempt a fix. I just haven’t taken time off to devote a day to it…tows like hell, but I’m at 14k miles and need to get it taken care of.

 

Hey Thanks , now you mention trailer I did feel it more with the Horse Trailer but I thought was the trailer now I’m wondering if wasn’t Truck to begin with , but haven’t driven with Trailer lately, maybe I need to test this as I know now ,Trailer is Top Condition as just got that looked at serviced / new tires …..have been letting the Tundra sit for while now because haven’t had time for all ReCalls , but needed it today & just feel the shake , without trailer, I’m at 17,000 , something doesn’t feel right

 

I feel it most going up a slight incline, but when towing and it hits 60-65mph is about when it shifts to 8th. If I manually shift to 7th I still feel it, but more prevalent 8th and above. I thought it may be the trailer, but happens with both trailers.

 

Yes this where I’m feelin mine at these speeds. Just gotta figure out how to prove it the Dealership took it out but they back in 15 mins & I know road they were on is 55 speed limit .

 

You’ll probably have to request a tech ride along. If you’re close enough to take a trailer, I’d do it and replicate the issue with them in the truck.
Good luck! I feel like the dealership will take care of mine, once I have a trailer behind it, I just have to make the time and bite the bullet.

 

Thanks so much ! Yea I do gotta carve time to Haul the trailer.
