It can be hit or miss. I have a HF impact that I bought in 2011. Not the earthquake brand, just the cheap one. With enough air it takes off everything I've put it on, though I've not had to remove commercial diesel truck wheels.

AvE on YouTube does awesome teardowns of lots of tools and shows the weak links. Some tools will surprise you.
