I remember autozone to be famous for DOA alternators and starters, the price is cheap so you try. I would rather get a good one and do it once even though money is a priority right now, have to figure in pain and suffering with that crap. Who the hell sells crap thats doa and not check them before a sale when they know at least 20% are DOA? I put a front half shaft in my GMC 4WD once, pulling out the driveway it popped and wham, I couldnt even go back to through it through their window. The CV joint looked worse than the original that busted.
