hey people this is my sometimes when i break my front right tire area makes a strange noise sounds like a bit of grit in the disc brake. i have checked both brakes on front (passenger and drivers side) and nothing in the break then i noticed the bar that comes from the middle of the car and goes to each wheel that it is covered in oil on one side and not on the other. im worried this is another driveshaft gone??? anyone got any ideas how to fix it or if it is something else other than drive shaft??
