I was having rear differential problems it started making grinding noises and didn't want to go over 10 mph without making a horrible noise. I need the car to go to Indiana on Wednesday morning. Any chance it will be done by then?
It should be...if you got it in this morning then it shouldn't be too long. Most likely the ring and pinion are bad, and its pretty easy to get your hands on the parts....if your mechanic has the right tools, its usually a 4-5 hour job at most.
