Front passenger seat shakes and wobbles

Hey guys,

Been searching around for the past hour to find a fix and no luck so far. My 2013 Tacoma DC's front passenger seat and headrest shakes when I'm driving 60-80mph. I thought it was an alignment/wheel balance issue but I had both services done and the the seat shake is still there. This appears like a common problem for 2nd generation Tacos....

Thanks in advance

 

Mine does a little as well but I'm running aftermarket wheels & tires. I added hubcentric wheel rings which helped some. Personally, I think think the wheels aren't completely balanced aside from what the shop tells me, but I could be wrong.

 

My '12 wobbles too. My fix was to make sure an attractive scantily clothed woman is always there to hold it down.

 

This is normal, mine has been doing it since day 1 of ownership. Just ignore it
