I think I know why he told you that but I’m not quite sure it applies to something like a crankshaft.

It was explained to me by someone who’s been doing it since dirt was new that it’s not advised to use an impact on a FWD axle nut, the shock transmits through the shaft(s) into the transmission and could potentially cause damage. I’ve never had a problem with it and the guy that told me said he’s only seen it maybe twice in 50+ years of working in the trade. Everyone uses an impact gun on axle nuts.

So there you go buddy, everyone agree’s.
Go ahead and use the impact.
Good luck!

I have actually seen this in service repair manuals on some cars. I have used impacts and never had a problem either.
Chances are you will do more damage to other things tugging on a cheater bar and wedging some thing in flywheel ring to break bolt loose.
I have seen Kilmer crank the engine with a breaker bar in place to break it loose. Now that I would recommend against that!
