I raise my truck and trailer until the jack clicks once (i.e. as far as it'll go without abusing the jack) and from there am actually able to get the 10th link in the notch, and rotate the latches without undue force. (I'm just below the rating of my weight bars so they recommended I try the 10th link before trying heavier bars.) My trailer runs beautifully after I retract the jack.
I raise it again before unlatching the chains, so there's not a lot of energy stored in the system to cause a noisy/scary disconnect.
