Squeaking front end over speed humps

[cjmdwyer]

A few weeks ago front end starting squeaking going over the lower "traffic calming" speed humps. Not the shorter, harsher speed bumps like in parking lots. Those are quick and it makes no noise over those.
For better lack of words, sounds like hooo hooo going over those or pulling into a driveway with the hump type of sidewalk entrance.
I can somewhat reproduce it if rock the vehicle back and forth by pushing on the top of the door frame.
Will have it looked at when I go in for next service.
Purchased it used from Toyota dealer with like 1000 miles on it, so no idea if there is some kind of a leveling kit on it. I can't see anything but it looks pretty level with no real rake to it.

Update:
I went and sprayed silicone on the control arm bushings and sway bar bushings and the noise went away. I just find it odd that they would start squeaking as they look stock to me, not some aftermarket urethane ones that like to squeak.
Also sprayed the rubber where the top of the strut/spring mount. So it could have been that as well. All I know is all I hear is gas sloshing when I rock it back and forth now!

well you are in az so the bushing can dry out pretty easily vs states with more constant humidity.

you might notice the squealing goes away after a rain shower for a while until the az heat dries them out again.


it is odd/rare being so new that the bushing dried out so quick, but not unheard of.
