CivicR has graciously placed a video of my car on his website.
During the last ~5 seconds or so, you can distinctly hear the wobble that I am talking about (while the car is decelerating). All suggestions are welcome.
Please take a minute and see if you guys know what is causing this noise.

The waah-waah-waah sound is exactly what I'm talking about.
I have taken care of a couple repairs recently, but the sound originated quite a while ago. I really can't trace it back to any one thing that I did.
What mods/repairs have you done recently... or better yet, did you make any changes to the car and the sound immediately followed ??? I heard no really loud noise... only the "whaah whaah whaah whaah" sound as you slowed.
could it be a bad wheel bearing under the load of braking ?
bent axle maybe ?
what about the bearing that is inside the haft-shaft ?
did you run over something or hit anything hard that you can think of ?
have you driven your car though deep water in the recent past ?
just some thoughts and questions .... [img]confused.gif[/img]
Hmm. . . never even considered the wheel bearing. In the vid, the car is coasting and not breaking. Don't know if that would make any difference.
You know though, I DO hit some hard bumps sometime. In fact, just recently (about 1 mo. ago), I changed out my left front shock b/c it was blown.
How would I go about checking the bearings?
Actually. . . I might have to eliminate the wheel bearing theory. My car makes the same noise at the same rpm while sitting at idle.
hmmmmmmmmmm .... well .. if it still makes the noise when the car is sitting still... you can eliminate the entire rolling chassis ... you have to think in terms of what is moving when the noise is present... if the noise is present even at a idle ... whats the only thing moving ?
the engine ... the electric fan possible ? ...
look for anything that might be rubbing up against the pulleys ... or something that might be rubbing against any part of the engine for that matter ... I had an electric fan that went bad in my car ... it made a funky noise before it died ....
What exactly is the RPM that the noise is present ?
Could it be a loose windage tray in the oil pan ? [img]confused.gif[/img]
the only time I heard the noise in the video was upon deceleration ....
does it make the same exact noise upon acceleration ?
is it possible to see and hear a video of your car making the noise at an idle ?

Icopas. . . I'll take a vid of the car making the noise at idle this weekend. I'll just rev it and hold it at a higher rpm, so you guys can hear the noise. Hopefully someone can host it (I can email it to someone).
It does make the same noise during acceleration. I was saying earlier that the noise starts at around 4500 rpm, but actually, I've noticed it even earlier (around 4000 rpm).

Are you braking? I warped mine, which is easy to do if you get the brakes real hot and then get water on them.
that was my first thought - warped brake rotors - thats sure what it sounds like - but it has been posted that the car makes the same sound standing still ... that eliminates brakes - rotors - or any part of the rolling chassis ..
I thinking something internal in the engine - or something is rubbing the pulleys maybe ...
