What Is This Annoying Squawking Noise! (Video)

Waddup guys, well once again the bird is making me spend more money lol, The other day i went over some speed bumps and heard my car squawk on the left side as i went over the bump. I already replaced LCA,UCA,End Links,Inner Tie Rod,Outer Tie Rods On Both Sides couple months back... Heres what it sounds like when i push down on the suspension...video below.
Thanks

That's something rubbing. Shock boot?
Only thing I can think of that would sound like that in critical susp is if the strut <> LCA bushes are totally shot.

Holy crap your suspension has alot of give. I thought with the suspension you have it would be stiffer. That sounds horrible.

You know what, ever since i got the eibach springs & kybs from tire rack i expected it to be alot stiffer but it seems like it got worse.. when i go over a dip in the road it feels like im just riding on springs..i kinda feel the bounce and a lil bounce pry 2 more times after that.

Did you check the sway bar out? Some people dont like the kybs, mine are great. My stock sport springs and kyb gr2's are alot stiffer than yours looks. Does she handle the twisties better after the spring and shock swap?

Well, dont take anything for granted, just because it's 'new'. I got lower ball joint squeak at ~ 20K
http://forums.tccoa.com/showthread.php?t=135867

also I had all indications of {a} bad rear shocks so I got new and found someone hadnt tightened the top bushing down on the previous install.

I changed them anyway cause the gas was gone but they could have waited if I'd checked them out.

Still it sound like a 'rub' and by that I mean 'not under load / weight pressure'. Did you check upper CA bolts? Guess the bush>fender COULD make a noise like that if the sleeve was moving

Well, that should change the sound but I meant disconnect the link from the sway bar, so the bar doesnt move when you push that side. It will probably move SOME still but ought to help isolate.

I'm sorry but you ought to at least remove that wheel and do a visual check on everything.. incl those UCA bolts.

loosen the sway bar bushings as best you can and squirt some spray lithium grease in there then see if it goes away. They are noisy when dry.

It is the sway bar bushings, they look pretty dry and move slightly when i push the suspension down, i put it up in the air and checked everything and when we lowered it just b4 it touched the ground i put my hand on the bar and i could feel it tremor and could pinpoint that it was the point of origin. Alan when i loosen the bolts do i have to do any precautions or could i just loosen them up and spray em?

Just loosen them up enough to squirt some grease in there. You could try a grease gun with a grease needle but I don't like to use that kind of grease on them. Lithium or silicon grease will not soften it up.

Ok so just go in through the top and loosen the bolts holding the sway bar to the frame just enough to spray the whole bushing down with lithium grease correct?

Same Problem But...

Sorry to revive this thread for my own car, but I have the exact same problem, squeaking/rubber twisting sound is exactly the same on my car, just on right side. However the solution being 'the sway bar bushings' doesn't work in my case, I'm pretty sure. My sound was there before I replaced my sway bar bushings with new Poly bushings, and it still exists (btw I can't see new poly bushings squeaking like rubber). Also have brand new UCA's, LCA's, end links, outer strut-rod bushings. I've had the hood open and bounced the suspension and listened, definitely coming from down low, maybe inner strut-rod bushings?

Actually I got the poly sway bar bushings from SCP to replace while I was already gonna be doing my LCA's, having it all apart, figured might as well.
But really, pretty easy to replace, even without the whole suspension removed. I would say just need to of course remove the wheel and sway bar end links, I would suggest disconnecting UCA (also pretty easy) just to get things out of the way. Then pretty much can be unbolted from above with a socket and LONG extension, unlessy you have very small arms to squeeze in there. The bushings, with a few shots of silicone as you go, will pretty much pull & twist right off. Reverse order for new install. Pretty simple actually.
SIDE NOTE: My post above about the squeaking, after driving a day on new UCA's & sway bar bushings, drove it tonight over speed bumps, and squeaking is worse, AND on BOTH SIDES.
Now I'm thinking it IS the NEW sway bar bushings. I used some silicone spray to get them on. I don't know, gonna try lithium grease next day off.

I chuckle every time I see someone say poly's dont squeak. When they first came available everyone raved about 'makes for better handling but they squeak terribly!'

I'm sure composition has changed but come back in 100,000 miles and tell us they dont squeak.

Factory rubber.

I'm sure someone makes a Delrin bushing also, but can't point you to one.

There is no CURE for the poly squeaking, but you can HELP it by drilling for a zerk (alemite, grease fitting, whatever you want to call it) and lubing them every 3K to 5K miles.

!I! prefer a moly-lithium blend personally, it's slicker than lithium by itself.

You can find PTFE (Teflon(tm) ) lubes also.

But even a cheap lithium will help

Still, it may squeak every so often, no matter what you do.

Wow, had no idea, just assumed that poly bushings wouldn't squeak, never installed them before. That's cool to know, thanks for the insight pettyfog!
Guess I'll have to take them back off and get some grease in there.

The reason why poly squeaks in this application is that it's too hard.

It doesn't yield, so the sway bar has to shift inside it. Which means that you've got hard metal on hard poly - which is where the squeak comes from.

Rubber's softer, so it yields slightly.

That's why you lube poly to get the squeak out.

THAT said - an occasional hit with a PTFE (Teflon(tm) generic) or moly spray will do wonders to keeping it DOWN.

Thanks Ralph, for the info.
Personally, I don't really mind the squeak, as I really only hear it as I'm going over speed bumps in cold weather. (used no grease on installation, didn't know I had to).:
But if there may be a problem of early wear on them due to non-lubrication, I'd appreciate any insight. If so, I gotta take that sway bar apart & do it right.

Thanks!

This squeaking/squawking, AFAIK, is primarily a noise problem, not a wear problem.

I'd still hit it with some PTFE spray every oil change, but that's me. (Actually, no - I bought the lubeable Energy Suspension parts to AVOID that squeaking! )

BTW - the ES parts? All you have to do is unbolt the brackets and cut the old bushings off - they have a split so you can leave the end links attached. I found it darn near impossible to get my fat hands to where I could lube them, however, so when I was getting the car aligned, I had the shop lube the chassis for me. They even hit my U-joints (I was watching them!), so all in all worth it to me.
