A weight distribution hitch will lift weight off of the rear axle and move some of it to the front axle and some to the trailer axles. If the rear axle was a fulcrum the weight on the axle would increase.
I recall well in the past an advertisement for a W/D hitch that showed a car hooked to a trailer with no rear tires. Can't remember the hitch brand but I belive the car was a FWD Toronado.
