Lots of Shaking in my 2017?

Haha!! Replace the whole audio system with better speakers and a few 12" subwoofers and you won't notice the shaking anymore... after the lift, tires, bumpers, and skids of course.

 

My '17 TRD Sport also has a vibration. It's noticeable from say 55+ but really noticeable at 70+. If I let go of my steering wheel you can really see the wheel shake left to right at a fast pace. Same issue with drinks and passenger seat as the OP noted. I had this on stock wheels and aftermarket wheels/tires.

Dealer apparently couldn't feel it when I took it in so I took the service manager for a ride and he immediately felt it on the hwy. Said to get my aftermarket wheels rebalanced and bring it back (yet again) if the issue persists. Well I got them rebalanced (road force) and vibration is still there, haven't taken it back yet...

Same issue here. Same run around, factory wheels need rebalanced, then maybe my aftermarket, having them do an alignment on Friday. Oh vey, $40k truck, shouldn't have to worry about this non sense.

 

Here is a video I took today. The 1st point is 70mph and the 2nd time I point its 80mph.

I also crawled under my truck just now and noticed there were different amount of weights on each rim and immediately thought I found the problem! But I called my tire/wheel guy and he said "no wheel has the same weight usually" . He thinks my back right needs to be re-balanced because my seat is shaking. He said when its the seats shaking its from the rear and when you feel it in the steering wheel its the front. He also texted me again saying how these tires are 10 ply and a lot stronger and stiffer so I should air down to 2psi lower than whatever it says on the door jam . This guy is very reputable in my area and deals with a lot of high end customers so I like to trust him. Thoughts?

Totally agree man, I went on a 215 mile trip north with the family this weekend and the steering wheel shaking/vibrations in the cab drove me nuts most of the way. I asked they check my alignment and refused to do it because they said there "was no need to check it".

My vibrations seem to not be present 100% of the time which leads me to believe it's some sort of bushing but hell if I know.

Turned out to be my alignment and they also road balanced and phase matched my wheels and tires. All good now! Pays to bring your service guy a six pack every once and awhile lol
