w124 steering wheel removal - impact?

[dlssmith]

Has anyone used an impact wrench to remove the 10mm hex bolt that secures the steering wheel?
On my older 124 the hex indent in the bolt head is rather shallow and using a breaker bar almost requires three people. One to hold the wheel from turning, one to bear down on the breaker and another to hold the breaker bar straight so the hex socket doesn't slip out and strip.
