Vibration in suspension?

I recently bought a 2018 TRD OR Tacoma. The dealer put a lift and some new tires on before selling it, Toytec lift and Falken Wildpeak A/T tires. I noticed a subtle vibration when driving that seems like its getting more and more noticeable and maybe I'm being crazy but it feels like its even slowing me down when I take my foot off the gas. It feels like an intermittent vibrate that starts and stops for about a second each time. I took it into the dealer and they said that when you put a lift on Tacomas that lots of them will naturally do this and that there's nothing to fix. That just doesn't sound right to me. Anyone with more experience with this have any input before I go head back in and argue with the service department again?

 

Brand new truck and their lift. Make them fix it.

G.

 

That's my plan but they keep telling me there's nothing to fix, which just sounds like a cop out to me.

 

needle bearing issue more than likely. Have you tried 4x4 and seen if it goes away?

If they’re refusing to fix it, have them document it. Drive it till something breaks and then they can fix it since it’s their lift that they personally installed. Or you can try a different dealer and explain the situation.

 

I haven't tried that yet. It was only noticeable at 45+ until recently it seems to be getting worse. I'll give it that a shot after work.

 

How many miles ? Just curious because I’m in the same boat except I haven’t took it to the dealer yet . I have a road trip coming up in a week an don’t wanna destroy anything.

 

It’s probably drivers side needle bearing, you can replace it with the ECGS solid bushing.
