hey all...i have a problem with my 99 3.0...i hear a squealing or a grinding noise when i am driving...kinda faint but it also happens more when i turn...could it be my brakes...i don't think its the power steering cause i see alot of fluid still there and it isn't as loud...would anyone have any suggestions...i would appreciate it...thanks....oh and if it is the breaks should i just go ahead and get new rotors for the front if they need to be resurfaced...and would i need the tool to undo the rotors...?
thanks in advanced...
