The 07 GT we just bought, that now has a little over 3000 miles on it, is at the dealer getting the rear axle whine fixed. After two failed attempts with new gears (replaced both ring and pinion twice), they now have ordered a complete rear axle assembly. I am not upset about this, I am actually quite glad they are doing whatever it taked to fix the problem. I should get the car back Tuesday or Wednesday. One thing that sucks is the slow ass Focus we have as a rental.
