Grounding question on my trailer large amount of flex

Ok where is the best place to attach the ground for electric brakes. I was going to just use the frame to attach the grounding wire to tthe brake wire but I started thinking about my poly bushings and how I didn’t want a grounding issue since what Ive been told is the biggest critical failure of wiring. Then I thought about attaching it to the axle and also use the frame. My setup has about 9” of flex and I really don’t want that much wire hanging so close to the wheels so this is my dilemma.

Looking for advice. Thanks

Great thanks for the advice on the ground. Any thoughts on the long ground wire I have to place on it and the flex. Could I use a spring and somehow attach it to the wire to keep it out of the way of the tire??
