Well I had to do it, now or never so I went and did it.Went to Sears and bought a new C3 1/2 drive impact wrench.To put it to the test, I had to change 2 flat tires on a large round bale buggy.It had been setting for ages. The old tire were dry rotted.Well the boss had soaked the lugs with PB Blaster so here comes my new tool.It worked great. All 10 rusted lugs came off with a bit of reluctance but off anyway.Wire brushed the studs and replaced the lug nuts. Entire job to less than 15 minutes.I got this for $89.95 +tax.For this price I cannot complain. Harder jobs down the line, Ken
