2017 Ram ball joints vs complete LCA

I did jack it up on the frame and everything was "hanging". I tried the pry bar under the tire and didn't notice any excessive movement. I'll try it again and swap front to rear.
Thanks.
Yup. Jacking under the frame causes everything to bind together under tension from the coil spring. You could still have a worn lower ball joint, but trying to help make sure before you spend the money.
