Hi All,

I have noticed that the passenger seat has a vibration that can not be felt anywhere else in the truck. You can actually see/feel it from the drivers seat when no one is sitting in it. However, you can not feel this vibration through the steering wheel, gas peddle, door panels, etc. It increases with speed with is present at low and high speeds. My thought is that perhaps the seat is loose? When sitting in it it feels like the back right wheel is out of balance but I know it isn't (recent road force balance and feeling in all other seats confirms this). I have searched this forum but have found nothing about this.

Anyone else experienced this? Could it be I just need to tighten the seat/tracks? If so, does anyone have a guide as to how to go about doing this? Thank you!

Wow!! Definitely a first! Tightening the seat against the track sounds like the solution. Of course, the passenger might be able to get a massage while you drive?

This happened to me a while back. It stopped after I changed my tires. Vibrations and resonance are a funny thing...a very slight vibration moving the seat in the right way will make it shake like that.

Or at least thats my theory.

There is a TSB for the squeak:

Click on #24, scroll down an open the pdf file.
The alternate fix is to turn the volume **** one full turn clockwise and the squeak should stop.

My current 2007 GX has done it since new and my previous 04 GX also did it......
