Do I really need an impact wrench?

[quick89gt]

I took mine to auto zone when i switched mine, and they did it for me really quickly, and i know they used an impact. i have impacts here at my house, but no vice or anything to put it in to keep it from turning. if there is an autozone or anything like that around there, i would just take it there, and they will have it done in 5 mins. josh
