140 ft pounds is a BIG number for standard 1/2" lug nuts. Normally these
are torqued to 90 ft pounds. At 140 you may not get them off.

Shouldn't be, when I put my summer tires on last april I put anti seize on
the studs and torqued them to 140 ftlbs. The ones that came off still had
anti-seize on the studs, no rust.

Are you sure your lug nuts aren't rusted onto the studs? You can borrow,
rent or buy a much more powerful impact wrench but you might end up just
breaking off the stud.

I have what I thought was a decent quality cambell hausfeld 1/2" gun

which

is rated at 380 ftlbs. All fitting are 1/4" M style and hose is 25' 3/8"
ID.
It will not remove my lug nuts from my chev 1/2 ton truck. I tried
pressures
from 90 up to 120 psi with no luck. It removed a few of them but some

will

not loosen at all. I am using 1/2" drive impact sockets as well. Anyway
are
these guns over rated, it is made in Taiwan. I noticed some ingersoll

rand

and even sears brands rated up to 600-700 ftlbs, is this what I need. I
tried a friends Chicago pneumatic and it would not spin the nuts either.
Also there is an Allen set screw type plug in the side of the gun and it
says oil, how do you know how much to put in? Thanks
