Hello again. I posted a question a while back asking about dana 70 s (fronts). Someone said to make sure it was open kuckle and not closed. I finnaly got some more info on the axle and it does have closed knuckles. What is so bad about them. I plan on putting this axle if i buy it on my truck with 44's and a worked 454 so i want it to be strong. Or should i just forget the whole thing and find a dana 60.
