Re: Dana 44 and 12 bolt 1/2 studs

I just put some longer than stock 7/16" studs in my front hubs. The longer studs had a larger knurled shank but the closest smaller drill size was 37/64" which was only .005 smaller. I drilled the hubs but the new studs didn't seem like they went in hard enough. I believe that .007 - .010 is recommended. I ended up welding them to the hub on the back side as I didn't want to take the chance on them spinning in the future. Just piece of mind.
