Suspension Diagnosing Help!
hi guys. im sure you all know that this squeaking problem has been discussed too many times. mine might be slightly different. you see ive been getting squeaks when passing through a speed bump. i did a test.
i did 3 passes on a speed bump with only the left tire going over the speed bump, NO NOISE.
i did the other side also 3 times, NO NOISE.
i went on the speed bump with both tires going over the bump and there was the noise. i did it several more times and it never failed.
My suspension is stock and never been repaired. had the alignment checked its perfect.
im planning on changing my springs soon to lowering springs. and while im at it i want to solve this problem so ill do the DIY all in one sitting.
any ideas what is to replace to remove the noise? ALSO! im getting vibrations on the steering wheel at 60mph++. FYI! everything is aligned and balanced. and shocks springs are in perfect condition also.
so again. question 1 what causes the squeaky noise?
question 2 what causes the vibration?
im running out of ideas guys. help me out.
EDIT: Rims are not bent either.

ok. i just checked everything today. upper control arm bushing is bad on left and right, $35ea. westcovina dealership and $55 dealership Riverside. and the sway bar looks ok BUT for some reason my swaybar is 1 peice $60 westcovina dealership and $95 at riverside, meaning i cant buy the bushings separately. What the heck? anyone have the same thing?
and also will these 2 parts remove the Vibration?

You didn't say what kind of tires you are running, but if you're running questionable-quality tires, the car will feel like it has an eternal vibration. You may even think that you have a bad wheel bearing.
Check the tires for cupping/feathering at the tread edges.
If you have a 1-piece swaybar/bushing system, then don't bother replacing, as this won't squeak.

tires are BNEW pirelli nero zero. just bought them alike a week ago. not the wheel bearing either.
thats the thing with the swaybar i need to know if anyone has a 1 peice. everyone can replace thier bushing but i cant. OR the stealership is saying its a 1 peice so i buy the whole thing. im pretty sure now that the squeaking is from the sways but if your saying it cant squeak coz its a 1 peice then what else will squeak?
also want to know if it could cause vibration.

Do you have wheel spacers? I'll put money on the problem being spacers. Are they decent hubcentric spacers?

I know nothing about them - H&R & eibach are OK - people have troubles with many others. Remenber to ONLY use ball bead lug bolts.

Reviving an old thread here...
Recently Ive noticed the infamous squeaking sound from my cars suspension. I did the following test:
Parked the car on level ground and then to each corner one by one and pushed down on the car.
Results: No squeaking whatsoever from the front two wheels...very little squeaking from the rear left wheel and major squeaking from the rear right wheel. My guess is that the problem is with the rear right suspension and I heard squeaking form the rear left as well because when I pushed down on the rear left, the rear right suspension compressed atleast a little bit...thereby producing the sound.
The sound itself is like an old spring mattress being compressed.
Are there any other tests I could do to help identify the problem?
There are a few threads around here describing what i think is the same problem and the solution being to silicon lube/replace certain bushings/sway bar..
Is this an easy DIY? Any pics/schematics that would help?
Thanks guys...
