anyone re-used the crush washers on their rear diffs and had any leak problems, or has it been ok? reason im asking is because the dealership here are "fresh out" and have to be ordered!! still not sure why they wouldnt have any 99cent washers in stock?? anyway, think its ok to reuse them?? and i also tried autozone, but they said truck was too new, so they didnt have a listing yet!!
