2006 Mustang GT-Rear differential repair cost?
How much to repair the rear differential on a 2006 GT? I brought it into a ford dealership due to a significant whirring noise coming from the rear end and I got quoted at $1100 to replace the rear diff bearings, pinion, seals, and races. I was told the main ring gear was fine and didn't need to be replaced. I'm no mechanic, but what I take from this is my actual gears are fine, I just need a new gear install kit...and if so, 1100 seems steep.
Also, I bought the car less than 5 months ago from a non-ford dealership. I bought the car knowing the previous owner had done some work to it. (had 4:10s installed) The dealers warranty expired after 90 days, but is it possible that a problem like this falls under the lemon law?
Mustang is a manual 06 GT with 37000 miles.
