GX 470 Squeaking Diagnosis (1 Viewer)

[wraith75]

recently purchased a 2003 Lexus GX 470.

I have the sunroof rattle that I am going to take to a toyota dealership to "adjust" at some point. I also have this squeaking noise that is coming from the rear of the vehicle. Can anyone tell me what this is? Any guesses will help! Short youtube video with the noise is here

Still running stock suspension I did lube all doors and sprayed some garage door lubricant on all the back seat areas that contact metal. I also removed the tool kit in the back along with the third-row seats.

Those little noises are always the best.

Have you pulled that panel off yet? Might be time for some hardcore process of elimination.

Also, are you able to mount a camera to the underside of your car? it could be something like a sway bar mounting bushing or even your spare tire not fully tight under there.

Is it just me or does that squeak sound like water trickling?

My similar squeak disappeared when I removed the spare tire.

My similar squeak disappeared when I removed the spare tire.

let me try that! it makes sense my spare tire is old (probably 17 years)

Removed spare tire and front sway bar bushings still not able to find out what this squeaky noise is. When the car runs through a car wash or rains the squeak goes away. Also shot silicon lube on most of the undercarriage to no effect.

Update on what this noise was in case anyone gets the same problem

Took to lexus and found that the bracket for the right rear shock was hitting the suspension arm on top.

I have the same exact issue and I've spent over 15 hours total removing things and adjusting things with no luck. I'm hoping you have found an answer? Pretty please and thank you.
