You'll find LOTS of other uses for that impact wrench down the road!
You will no doubt kick yourself for not buying one earlier!!
QUICK STORY...
Back in college (a very long time ago...) I bought an old rusty VW Bus (Van) for a couple hundred $$.
Brakes were only working on the front wheels, so I decided to pull the rear drums in my apartment parking lot and see what the problem was.
This was one of those VW setups where the rear drum/hub combo is held on by one BIG center nut. I spent close to an hour with a huge breaker bar, cheater bar, and a small sledge hammer trying to get that nut free. It simply wouldn't budge (probably because the Bus had lived near the ocean for a few years).
I decided to take a beer break, and while I was standing some 20 feet away from the Bus all of my efforts finally showed some results. The Bus fell off the jack and landed right where I'd been sitting 5 minutes earlier!
I then decided it was wise to take the Bus to a mechanic.
He grabbed his air-impact gun and that bolt spun right off in an instant!
1st Lesson Learned: Use the right tool the 1st time.
2nd Lesson Learned: ALWAYS use jack stands.
3rd Lesson Learned: NEVER sit with your crotch directly below the brake drum!!
(Hopefully I'm smarter now... Hopefully....)
"Cheers!"
