I think the impacting has an effect, else the tools wouldn't have it (it 
requires clutches and other extras that must be there for a reason).

I'm thinking a resounding yes.


I've got one of these:

My only gripe is that it is single-speed, not variable speed.

But it's handled anything I've thrown at it.

Lists for $150, often on sale for $99.

Might want an impact rated socket to match the lug nut size.


Also, like Evan said, penetrating oil (can use ATF fluid instead).


Also, application of heat to lug nuts can expand them enough to help - 
got a torch?



Good luck.
