I own an EF falcon, 1996 model, futura, straight 6. Its got about 188000 kms, and normally runs fine. Recently me and my mates were doing donuts on a patch of grass, and when I excited the grass, and began to turn, the wered clunking and scraping noise was heard. It only happens when my car is turning, not when in a straight line. Wat do u think the problem is?
