So how does one know what torque is being applied with an impact driver? Do you get it close then measure with a tool?
You don't. When I put on a lug nut I don't even tighten. I just spin it on till it barely ratchets and then stop. The rest is done with a torque wrench. Most Class C E450's are around 135 - 14 and most trailers are 75 to 95. That means you have to start 20 pounds back from there to use a torque wrench. The impact wrench sure is nice for spinning them off though. Use a torque wrench to put em back on and then check them 50 miles down the road again.
