So here is the deal. If I start driving my car after a long period of being parked, like an overnight, I start driving it and everything is fine. No squeaks. BUT, If I drive it for a while, lets just says a couple of hours, once I go over speed bums, heck even when im at a light and give it gas, it makes this horrible squeaking noise. Kinda like when your rocking a bed with a bad matress

Im just trying to figure out what it is. I push the car from the front fender down, and it makes the noise. If I shake it from side to side you can also hear it. Im just trying to figure out if its the Shocks, maybe the Top rubber piece where the springs rests or maybe A arm bushings ???

Any help would be appreciated

Interesting. What mods have you done?

Do you have any urethane suspension bushings?

How old and what brand are your shocks?

Tell more about your car.

The car has 78K miles, Stock shocks and springs. Currently the car is all stock except for a Lid and the GMMG exhaust.

I am not sure what is wrong. Try this. When the car is making the noise, have an assistant push the fender and replicate the noise. While he is doing this feel the lower shock body, then the upper mount, swaybar etc. Keep putting your hand on various parts until something vibrates in a method similar to the noise.

As f-body's are fairly low, you may want to put the front tires on 2x10's to give you enough room to reach under it.

Back when stock my car would do this too when driven for like an hour or so. Sounds like an old bed creek.
Replace the swaybar endlinks.

Use Marine grease as it resists water better and will last longer.
