Default suspension problems

so i went out and bought a grease gun so that i could make sure everything was lubed up. I got every single moving part and my car still creaks like no other. I made a video driving over a speed bump. Hope you guys can help!

It's probably your upper control arms. There may be grease fittings on each end of the bushings, there may not be. You can add them if you take the little bolts out but you may not be able to get any grease to go in. Pull the front wheels and take a look. Good luck.

Can you determine if the noise is coming from the front or the back?

Can you push down on the car and get the noise?

As Daze asked, Poly bushings?

Sway bar bushings?

Leaf spring bushings?

Hell, turn up the radio.

definately sounded like front as it only happened when the front went over the speedbump and not the rear. Odd.

Ding Ding Ding we have a winner. Poly is horrible about squeaking. If you grease all the poly bushings the squeak will probably go away. Also if you are running poly strut rod bushings and original strut rods I would replace the bushings with rubber or the strut rods with new. I know of at least 6 instances where the stiffness of the poly caused the old strut rod to sheer well driving.

Do you think the strut rods are what is squeeking?
