    are you sure that it is the front diff and not the t-case, u-joints, or CV shaft? My warranty company put a new front diff in my truck because they thought it was bad. It turned out to be a bad t-case. They replaced that also. You can always pull the front drive shaft, put it in 4x4 and see if the noise is still there.
