Those are strange problems, aside from the rear diff. I'd move up to a newer one if you really have those problems.
Not an expert on this, but I think if you have something major like this repaired under warranty and it keeps reoccuring, you may be able to get it fixed again.westonddean said:...and right at 59k I began to get a strange hesitation if I were to slow down quickly then gas again. This was fixed under warranty ... Anyways the problem has come back yet again and I'm right at 63k so I have no warranty.
