Update/Edit: Thanks for all the input, guys. In the meantime I have just about completed the struts - and sway bar links since I'm there and they're cheap. It sounds like the DCF891 would be the best to start out with and go up from there if necessary.
I'm getting up there in age and I'm the middle of replacing struts on my SUV. Every nut and bolt has been a struggle. I think the last shop to do the tires must've used an impact wrench and I've had a hard time getting the lug nuts off. Eventually I had to use a hydraulic jack to push my breaker bar up for all of them. And that's just to get the tire off so I can start replacing the struts.
I started to complain here about how many joints in my body hurt afterwards but I'll just get to the point.
I don't do this work often but it's caused me to start looking at impact wrenches. I have a good shop compressor so an air tool would be fine. I'm on the DeWalt 20v and flexvolt platform so that would probably be a better option since it's more portable than dragging an air hose out.
Are you guys happy with DeWalt impact wrenches for this kind of work?
I'm tired, boss.
