Rip, knowing what I now know, I would not have gotten the cheap Harbor Freight wrench. The fact that it is still in literally perfect working order is just dumb luck.
Frankly, in many ways it is more important for the newbie to have a reliable tool for torquing the lug nuts. If I inadvertently over-tighten the nuts, I run the risk of being unable to loosen them while stuck by the side of the road in the desert. If I severely under-tighten them, I run the risk of losing a wheel.
Which would be a bad thing, since I have a single axle trailer.
And the same is true of my truck's lug nuts. A while back, I got an oil change from my local Jiffy Lube, and they rotated my tires. I always double check the torque after a tire rotation -- only the paranoid survive, right?
Well, this time I could not even get my socket onto the lug nuts after the Jiffy Lube rotation. My next oil change was done by a real mechanic. When he tried to rotate the tires, he told me that someone (Jiffy) had used the wrong socket and had rounded the corners on my lug nuts and that I needed new nuts!!
Apparently, the Jiffy folks used impact wrenches (of course) and had set the torque on the wrong setting.
My new lug nuts now work fine. I no longer let Jiffy touch my tires. And I am still going to double check the lug nuts whenever anyone other than my mechanic rotates the tires.
