I bought this 2 months ago and installed it on my truck. I've driven less than 4,000 miles and it's failing and needs to be replaced. Will they stand behind him and replace him? If not, I will never buy parts from them again. Sometimes I can understand the bad part, but I can't understand a company that doesn't stand behind what it sells. Send me a new one, I'll install it and give you another chance. My apologies, when I tore it up I found the other side wasn't ok. It's good. I never heard a word from Detroit Axle when I thought there was a problem which makes me wonder about their customer service. I've raised my rating to 3 stars, I would rate them higher if I ever heard from them.
