My 87 Ford F-350 ran rear wheel antilock brakes, and a load-sensing proportioning valve. When my wife's nephew ran it out of rear axle lube and roasted the gears and bearings, I replaced it with a GM 14-bolt axle. I had to disable the RWAL, but the load-sensor stayed put. Even without the antilock in operation, it was difficult to lock up the rear wheels, even when running empty.
