Well buying the impact air gun it said it was 650ft lbs of torque. I was able to seat them, had to get another nut between the face if the axle shaft and the lip of the nut so they didn't contact each other and keep the nut from seating.

Also the 24v impact gun I have is 150 ft lbs and it definitely didn't seat them.

One side is in. I'll work in the next side shortly, trying to figure out these axle seals

well, I agree with him, no way in hell that stud survives 650 ft lbs. Specs on 1/2-20 those for breaking/shearing torque is 300 ft lbs. So while your guns may be rated for that max torque, I highly doubt you got them at peak torque. I just replaced my Jeep's 1/2-20s, which are the same diameter and thread pitch last week. Pulled them in with a torque wrench set at 150 lbs pounds, and I stretched the first two of them putting them in, luckily I had spares. I backed it down to 115 ft lbs, which was less than the factory recommends the wheels be torqued to when installed(125 ft lbs) and they went right in, undamaged.
