If you live where I do you can’t get anything apart in 1/2 hour on an old car that has spent 6 months of the year being bathed in road salt. I once saw a shop spend all morning trying to get the rear wheels off a Pontiac AFTER they had the lug bolts off. They had the car on a lift and had some good sized guys swinging sledge hammers after dousing the wheels with penetrating oil-all to no avail. They finally got out a torch and had to heat the center section of the wheels cherry red to get them to break loose.
