First pass: WDH Activated
Steer Axle: 4340
Rear Axle: 4280
Trailer: 5560
Gross Combined: 14180
Second pass: Spring Bars removed
Steer Axle: 3980
Rear axle: 4820
Trailer Axle: 5380
Gross Combined: 14180
Third Pass: Tow vehicle only
Steer Axle: 4380
Rear Axle: 3720
Gross Combined: 8020
I'll save you the math since my spreadsheet already did it all for me:
Weight Distributing Hitch Effect
Weight levered off the rear axle: 540
Weight transferred to the steer axle: 360
Weight transferred to trailer axle: 180
By my calculations, that's exactly a 1/3 - 2/3 distribution of the weight it levers off.
And point to note: That's NOT the same thing as distributing 1/3 of the tongue weight...
780lbs of tongue weight transfers an additional 320lbs off the front axle to the rear axle, increasing the rear axle load by 1100lbs. The WDH transfers 540lbs off the rear axle, and distributes 1/3 of that to the trailer, and 2/3 of that to the front axle.
Make sense?
