I have read all the post about underdrive pulley installs and i got the idea you need an impact wrench to take off the alt pulley, which i dont have. Well the only place near me wants to charge me 20 bucks to take it off!!! I really want to get these pulleys swapped out tonight. Anyone know if there is a way to get this done without an impact wrench? If so any helpful tricks?

 

leave the belt on car and car in gear and take it off

 

The belt will just slip if you try that. The impact is about the only way. I had one at hand, so it was easy for me. I did a write up on this a while back.

If you are willing to trash the stock pulley you can always vice-grip it, but that's pretty ghetto.
