No luck getting the wheel lug nut off ... even after heating with a propane torch. So I did the "sure-fire" thing: I took my 1/2" electric drill and drilled down through the lug nut and wheel stud. Hard job, not pretty, but it worked.
Next, I discovered that ALL of the lug nuts on all four wheels were apparently tightened by a crazed impact wrench cowboy. No way I could budge them. Today, I rented an electric impact wrench and finally got 14 of the remaining 15 lug nuts off. Well ... At least there is only one more nut to be drilled out!
This is going to a long project!
