Wow thank you for all this info! The mechanic doesnt speak very clear English , but he did lift the car and showed me the "Driveline "area and there was a grinding noise coming from it . This part was under the center line of the car , running from the front to the back of the car . Can the "driveshaft "and "drive line " be similar or the same thing ? He said the driveline kit would be about 700 for parts ....
