4 12 bolts axels have died in the truck now the last one was only 150 miles old! Has any one put a dana 60 or a 6 bolt 14 bolt in to a blazer or early truck? I have used both aruborn and ARB dif's to of the husing have even been broken! And yes I do have alot of tork and lots of gearing. though the rear ends have all had 3.73 gears in them I run a 4500 trany with a 203 rang box and a 205 transfer case so low in about 96 or 98 to 1. Even useing 80% of the given tork it works out to over 46000 LBS at the wheel. Any thoughts on this would be nice.
