If you find you cannot transfer enough weight to the front axle of the truck, even when the Hensley jacks are drawn up to their maximum recommended amount, then I would suspect that the WD bar socket bushings in the hitch head need to be replaced. That is a very simple task.
First you remove the bars, The remove the small bolt on the bottom of the hitch head right between the two bar sockets that holds the bushings in the head. This will allow you to remove the bar bushings and inspect them. If the inside edges are worn thin where the bar pushes against it, then simply order new ones from Hensley. You will notice an immediate improvement in the amount of jack raising necessary to achieve the needed weight transfer.
