The "Hensley bump" has absolutely nothing to do with the strut bars or their adjustment.
It is a real event and is caused by the truck slowing down much faster than the trailer, usually during a turn, which causes the hitch head to come forward, and due to the linkage, the hitch head will swing to the side and "bump" against its' travel limits which is felt as a bump against the rear of the tow vehicle.
This whole thing can be prevented by having a properly adjusted brake controller and properly operating brakes. The controller must be adjusted to "lead" or make the trailer brakes come on slightly before the truck brakes. This is easily accomplished with the Prodigy and many other controllers due to its' boost technology and the fact that the truck brake lights come on a bit before the truck brakes actually engage.
This allows the hitch to constantly remain in tension which will not allow the trailer to catch up with the truck.
One more comment. The "bump" and "sway are two completely different things and are not related to each other.
In addition, I have been the moderator of this forum almost since its' beginning and have never deleted any post about a problem with the Hensley hitch. It is possible that some posts have been deleted if they mentioned pending legal action but nothing because of any pressure from outside sources. I cant speak for other forums or websites.
