Well a 100# increase on the front and 86# increase on the trailer axle doesn't add up to 413# loss on the rear. As your total rig weight shouldn't have changed when going from a non-WDH to a WDH configuration, something seems wrong.
Just to clarify, here are my recent numbers from two passes on a CAT scale
(I also did a third pass with the TV only but that's not relevant here):
Truck+Trailer with No WD (spring bars removed)
Steer 3000
Drive 3960
Trailer 3460
Total 10420
Truck+Trailer with 3 link free WD (6 links under tension)
Steer 3280
Drive 3520
Trailer 3620
Total 10420
The Totals are the same.
The WDH decreases the drive axle weight by 3960-3520=440#
The WDH increases the steer axle weight by 3280-3000=280#
The WDH increases the trailer axle weight by 3620-3460=160#
And the changes add up: 160+280=440#, as the Totals are the same.
Yours #'s apparently do not add up, so you're doing something different?
