every time i brake or go over a bump it makes squiky noise??
is it cause i need greese job???
i bought it used and ever since i left the dealership it makes noise!!!

 

do you have a hard top? Cause if you do, it is the rubber gasket on the hard top rubbing with the rubber gasket for the soft top on the rim of the windshield. Mine does it sometimes when it is cold out. Its annoying, but worth it.

 

You'll need to provide more detail, but why not just take it back to the dealer you bought it from?

Front? Rear? Both? Metal squeaking sound? Rubber sqeaking sound?

The only squeaky noise I have ever heard is the rear sway bar bushings. I pulled them off and lubed with silicon grease. This happened at about 95k miles.

 

my car is still to young for that kind of problem. But yea, take it in if you are worried. And especially if it is a metal scrape/squeek.
