leaf spring torque

I don't know how to explain it any better. I don't know the physics of it, so I cannot put it into better words. If you don't believe the Mopar suspension book and almost every other leaf spring article you can find, I don't really know what else to tell you.

I didn't mean that in any smartass way at all. I don't know how else to put it into words. Other than to say I have tried it several ways and the only way that allows the rear suspension to work without binding is torquing the u bolts to 45 LB FT with the weight on the tires, or jack stands under the rear axle. As long as the weight is on the springs.

Well said. You can also dent/damage the axle tubes if they're too tight. I noticed less creaking and popping when I re-torqued mine.
