Question from Ron Gratz post in a sticky

As said going on the scale is really the only way to know for sure what's going on and where the weight is. When you sit just the tongue weight on the hitch the rear of the truck goes down and the front goes up. This transfers additional weight to the rear axle from the front axle of the truck along with the tongue weight. So if you were to use the WD hitch to lower the front of the truck back to its original height you transfer that weight back to the front axle where it came from in the first place. Now you are also distributing weight back to the trailer axles too but surprisingly youll probably end up with 90% or more of the tongue weight still on the rear axle. The amount distributed is a little different on each vehicle depending on the distances from the ball to the tow vehicle rear axle and from the ball to trailer axle center line. The new towing standards say to only restore about half the rise distance on the front of the vehicle to lessen the chance of jack knifing under heavy braking. Now this may leave the rear of the vehicle down further than most people like but don't stress over it. Most newer trucks have progressive rate springs so let the weight settle down on the heavier springs, that may require dropping down an inch or may be two. Check your vehicles owners manual for specifics on WD setup.
