It had an unfinished 4-link when I bought it, with the lower link mount forward on the axle housing. I was not thinking about anti squat when I built a new axle and trailing arms with an under mount. I did not redo the frame mount on the lower link, so I had the exact situation shown by the dotted line in my sketch. The upward force vector actually lifted the back of the truck. This reduces traction by shifting weight forward, it fights the suspension stroke, and it makes the truck endo over jumps. Class 8 trucks are known for kicking over jumps, and I think excess anti squat is the real reason why.
