There is a centering pin between the spring and axle. Its purpose is to ensure the axle is properly positioned on the spring. The axles "U" bolts then "lock" the axle to the spring. The "U" bolts should be checked periodically and torqued to the appropriate tension.
The cause of your problem was loose "U" bolts which allowed the axle to shift under braking or acceleration. You wrote the "U" bolts were tight. How did the axle then slide to 30+ degrees? As the angle of the axle to the spring decreases from 90 degrees to a smaller value, the "U" bolt will naturally tighten due to the deflection. It is rare for the centering pin to break, but if it did, the "U" bolts should hold the axle in place.
RichFAA can elaborate on this failure as he is another victim.
Replacing springs every two years is a $$ maker for the mechanic.

Yes we had that exact failure on our 06 3400 in 2007.
