Ingersoll rand or Chicago Pneumatic. these two pretty much make all
the store brands that are worth a crap (i.e. craftsman). go to Sears
and buy the one that's about $100... it's fine for the DIY duty cycle.
The wheel doesn't matter!
The rotor sandwiched between the hub and the wheel is what matters.
The thickness is no longer what it once was, and just a little too much
squeeze, and especially more in one lug than the other distorts the flange.
Then you get brake pedal pulsations, no matter how many times you cut the
just my two cents!
Yes, it really matters. My original post was for a pneumatic impact
wrench. They have adjustable torque but that doesn't mean you can
"torque" a nut or bolt with it. A torque wrench allows you to tighten
the nuts/bolts to the proper torque setting. Too tight and you can't
change a flat on the side of the road in addition to the possibility
of warping your brake rotors unnecessarily.
Zip 'em on, zip 'em off, tear up the threads. Impact wrenches should be
used in short burts because if you zip off a nut in one continuous
burst, the threads overheat and can seize up. Pausing periodically as
the nut comes on or off allows just a little bit of cooling within the
thinner parts of the thread structures.
Best way is to clean the threads, apply a small amount of neverseize,
and apply them with a crossed spinner wrench. With my chevy C-20, I
never tighten them much over 100 ft-lbs. Not only that I insist the
tire guy doesn't tighten them any tighter either because I have had to
remove them in the middle of nowhere. (Never had them come loose in
400,000+ of driving miles).
Any model of Ingersol Rand. Even the cheapest one will do the job for you. I
don't remember the model number of the one I bought back in about '85, but I
give it a couple of drops of oil every morning and it's still working like a
This is the one I bought. About $200 including cover.
