Suspension dump

[marek4792]

Unhooking the leveling valve rod usually works the best in this situation. I find this situation quite ironic because it was probably caused by someone without a dump valve dropping their trailer high enough to relieve the pressure from the truck. Then comes the next guy to hook up to it and it's now entirely too high and you get the above and if billy-big-rigger is backing up at mach-1 also ends up with crushed cab extenders and cab before they realized they jumped the kingpin... Ideally you want to put the legs down just enough so they touch the ground and an extra turn or two, activate the dump valve wait a moment for the landing gear to take the weight then pull away from it, preventing the next guy or yourself from high-hitching, or lowering a now loaded trailer with a slighly binded landing gear...
