I've been looking around trying to make myself self-sufficient while living in an apt. with my car RIGHT underneath my balcony in the underground garage. I have room to work on it, but need air tools. Thought I'd go with a strong electric impact wrench to help out. Anyone use one before? Axle nut needs like 250lbs. of torque to take off?? I KNOW air is the way to go, but can't store a big enough compressor to make it worth it. Anyone mess with an electric one?

How much torque would I need to get most jobs done?
