Yesterday took a left turn from what I had planned (garden) to a get the skid steer broken wheel studs out.
I hammered, heated, then drilled a pilot hole to keep a punch in, sledge hammer, then a air chisel with the punch tip,
After a few hrs, hands sore from hammering.
I went and got a buddy with the Popeye forearms to help.
4 hrs later we managed to get the 3 studs out of the hub.
Buddy left and so I got on to putting the new ones back in-

(Took 2 hours)
No room to hammer them in from the backside, just enough pressure to get them from spinning and using a 3/4" impact gun to suck them in.
The gun an extension was some hot when that was done!
One thing about doing this job was the cost. $75 for parts, and a $50 for buddy (he asked for $40)
If a mechanic had done this in a shop or on site-@$130+ an hour?
I know that no matter how experienced a person is there's only a few options in certain jobs.
Even heating/best rust releasing products/tools didn't work-just a lot of hammering with a 8 lb sledge.
I can see where the previous owners might have neglected in replacing the broken off studs.
I stand by the old saying "If it had been easy-It would have been done-101"
