Nice job on the drawing, Ken. I would really like to see a side-view of the pivot points. After re-thinking this system (in my long post), I totally agree with you.

5555 is a pillow block fixed to the lower arm (that the top portion pivots on). That's the key. In your drawing, it is noted that all the U-bolt and cradle parts are part of, and fixed to, the axle assembly.

Three mounting points on the lower arm will stop all pivoting. If the back rubbers are torqued tight and the wheel hits a bump or hole, the upper arm (C-D) will tend to snap off.

But, if we allow space between the rubbers, they will 'slap' and cause noise (in both directions). I'm still not comfortable with the center sleeve sliding in the lower arm hole steel. That's just plain wrong, and that is what messed me up.

But you're right, Ken... if the rubber assembly is designed to limit motion, they just transfer torque to the adjacent sides. That's wrong, too.

If this were my car and I HAD to live with this setup, I would omit the rubber assembly altogether and run with nothing back there. I do not see what purpose the rubber serves, that the shocks don't already cover. - Dave
