i have a volvo c70
i made a U-turn in my car and it made a scraping noise, i did some research found out it was my struts that needed to be replaced.

if you can help me, i am worried.. the car vibrates, makes noises when i turn, and reverse and wierd stuff, while turning.

Is it the Struts... or not, or struts and some other stuff.

Dealship is closed sunday, i have school mon-fri.
It safe to drive the car or not.

Also, by the rims, there is some greasy stuff, on the disc brakes, the ROUND thing, i dont know what its called, i quess brake pads.

Certainly sounds like a suspension failure of some sort, not safe. Get the car picked up, don't drive it unless it's a very short distance to the repair shop - particularly if it has grease/oil on the brakes...

edit: the oil/grease may well be from a dead shock absorber. If that's the only problem then it shouldn't be too expensive to replace the shock...
