Seat and cab vibrations at 65-80 mph

Hey TW, I have a 2016 sr5 4x4 v6 auto. I notice that when I hit 75mph the seats start shaking. Sometimes it's hardly noticeable, other times it's almost violent. I have the stock hankooks on my truck. They have been rebalanced and rotated. Any Ideas on what could be causing the vibrations?

 

I've corrected this on a few new trucks by simply balancing the tires. My first PDI on a Tacoma limited had the seat shaking like crazy and I was able to fix it with a simple rebalance.

Have you tried different shops? Or just through warranty at the dealership?

 

Warranty at the dealership, maybe I'll take it to discount tires. Not a huge fan of my local dealer. I told the about the problem, they came back saying it was "just mudd". I know for a fact though they have been rebalanced. Hopefully I can get some better tires soon. These hankooks suck.

 

I have the same problem. Sometimes it's there, sometimes it's not. Dealer couldn't reproduce.

 

it's been around for a long time on the tacos. I have the same thing
now and had it in both prior tacos as well.

 

Phantom seat shaking.... check! Mine comes and goes as it pleases. Had it with the Factory OR wheels and goodyears and have it with current set up of TRD Pro's and BFG KO2's. Doesn't really bother me... i kind of miss it when it takes the day off.
