Rear axle play

[movario]

Ok, so today I had the first try for the state inspection. As expected, I failed. But all the defects or "problems" the inspector stated were minor (like shutting down the turn signal in the mirrors, or some paperwork issues). Only one problem is a little more difficult. The inspector said that there is axial play on the rear axle. That of course is normal, but they aren't very used to US-Trucks with a rigid rear axle, so he said that the rear axle is faulty. Can anyone send me a pdf file with the information from GM how much play is acceptable? Like a screenshot from the Service Manual oder something like this.
