about 2 months ago i began noticing a crackling sound. to me it sounded like a spring shifting either compressing or decompressing... i only hear the sound when weight shifts around the car... like opening a door, getting out of the car, one wheel being elevated higher or lower than the others...

i was a little annoyed by the noises, but figured it was just something the cold weather was causing... about a month ago i replaced all four Michelin pilots tires with hankook v12's. before and after wheel alignment i noticed more body roll when changing lanes and turning.

i am using the same size tires and the same tire pressure as before with the michelin's. i havent had any traction problems on wet or dry roads.

although i didnt notice the body roll issue before replacing the tires, could it be a suspension problem? as far as i know the entire suspension setup is stock... although other Z owners have said my car sits a lot lower than their stock Z's...

i have tried manually pushing down over a wheel well to check for excessive bounce... it didnt bounce.

 

Take the car to a shop and have the suspension checked.

 

will do.. thanks for the fast reply...

i enjoy your avatar.

 

Could be swaybar too. Definitely get it checked.

 

One important fact you are omitting. How many miles?

 

Could be a broken endlink and your swaybar is no longer properly attached. Should look the similar in the back. This pic is my front right side.

 

You could be having some vertigo problems, lol
