Hey, I've heard lots of crap about the Cardone brand shafts. Check the NAPA warranty .pdf file on the web page for the shafts. They're Cardones as well. It would seem that Cardone supplies both the remanned and new shafts. There can't be that many companies out there with the tooling required to manufacture CV shafts. I'm sure that the only difference between many brands is the box that it comes in. I bought the new ones when I did my front end last fall because there were NO remanned ones in stock anywhere. So far so good. I measured the length of the shafts before installing. They were the same. I've been out wheeling a few times, have had the front suspension hang in the air a couple of times and have not had any problems. Maybe Cardone got their **** sorted out.
My $0.02. That's all.
