When Henry installed mine and gave me a demonstration on hooking and un-hooking, I lowered the legs and chocked the wheels then raised the front legs listening for the air to escape from the hitch then use the supplied breaker bar to release the hitch, now there have been times when that was hard to do so like others, I will release the truck brakes to let it roll which ever it wants to so tension is off the hitch then i have been able to release the handle with the breaker bar and pull away. I have never had the issue you seem to have, plus I have a lube plate on my kingpin.
