Socket was just worn larger. Steel wears off quick when you use the same socket day after day, so yeah an old, worn socket would be about 1-9/16, loose as a goose. When they finally start slipping on the nuts, we’d throw it away. New socket was tight, hard to get on the nut, and wouldn’t break em loose as well. Simple physics.
One inch impact running at 145psi. Man tools. For big nuts.
