What the F##K is squeeking?!?

**Raoul-Duke** · 04-29-2009, 05:30 PM

Sooo my z28 just started making squeeking sounds, it is nothing mechanical related (engine, transmission). It happens frequently when I'm moving, theres periods when it does squeek, and when it doesn't. I just put on new cross drilled and slotted rotors and ceramic pads on, back in September so I doubt its that, plus the squeeking has no relation to when I apply brake pressure or when I don't. It sounds like its coming from the rear, (suspension?) does anyone know what this may or might be or have had any similar experience?? Any input would be helpful brothas

You mean when you go over bumps? start siliconing the hell out of all that is rubber

**Eugenio_SS** · 04-29-2009, 05:57 PM

yeah it does but not just bumps, even when I'm just going along a flat surface mainly. Like when the car has been sitting for a day, at first it doesn't squeek, but after a ten minute drive or if i drive it a little agressive it starts then, silicone what exactly though? just the rubber bushing connectors?? any in particular?

yeah its kinda similar to that type of squeeking. I mean since theres no relation to my brakes it must be my suspension, right? Does this usually happen, it never did on my 94z, my 01 is almost at 60k does that have anything to do with it

If you dont want to swing for aftermarket stuff just lube up all the bushings. It will help

mine squeaked in the cold. ive heard the rear sway bar bushing squeak alot . spray some stuff on them

**SVG210** · 04-30-2009, 12:30 PM

I have the same prob... I have the non adjustable LCA's PHB and my right side squeaks. A bunch of White Lithion or Silicone grease will quiet it up.

Mine was the shock mount bushings.
I think. Stopped after I changed them, so I assume that was it.

**thearborbarber** · 05-04-2009, 09:33 PM

Put the rear seat back down and drive around. Mine squeaks like crazy some times. I need to adjust the latch bolts to put a little tension on the seatback to keep it from squeaking.

Can you get those aftermarket? I only found those from gm and the big piece was $194 each!

**c5z28** · 05-04-2009, 10:21 PM

And op silicone all that is rubber that you find underneath the car, I used marine grease since it stays in place under wet conditions. Pop out the lca's, panhard rod, endlinks, etc. It might help out some.

**random misfires** · 05-19-2009, 05:57 PM

i'd say the first thing to do is find out whether its coming from the inside or out of your car. second, find what side. if it is from outside, try narrowing it more to a specific area. how or when does it happen more? over bumps? just straight drivin over smooth roads? sometimes a second person helps. have a person ride in the back seat lookin for the squeak, or try drivin real slow past the person so they can hear what it may be. then, get back to us...

exactly where my squeak is coming from. Mine does it since the tires are bad and rims probably out of balance. on the freeway at 110 km/hr and up it starts to squeak with the slight vibration.

**5abivt** · 05-22-2009, 10:48 PM

mine is getting worse. It's not the seats and I replaced the wheels/tires today and it has gotten better but still there. I opened the hatch and wiggled it and not coming from there. i pushed down on the rear fender at the 1/4 panel and I hear it with the hatch open. I just got home from getting new shocks and springs installed so i doubt its the shocks. I'm going to have my buddy get in the rear and drive the car and have him narrow it down. also going to wd40 the hatch points and rear latch.

**5abivt** · 05-23-2009, 07:43 PM

I got out and pushed down on the rear quarter and it is definitely coming from something in the suspension. My guess is sway bar bushing. When I get a chance I will open it all up but my driveway is out of commission atm because of construction so i'm parked across the street

**MotorDogStar** · 07-25-2009, 08:21 PM
