Trouble tightening hitch ball nut
I know the specs ask for 4 50 pounds of torque on the hitch ball. I tried tightening it his best I could, but the best I could do is 300 foot pounds. Is that enough? The lock washer is completely flat and I can’t turn it anymore, and I can’t tighten it anymore on the workbench. This is on a true track Curt weight distribution hitch. I heard I can put it on the receiver and tighten it on the car. Can I do that and not damage the assembly? I’m worn out. This would’ve been easier before I lost weight!
