Yup...very simple fix. Someone did not install them properly or did not torque the U-bolts properly.

-Jack the axle up, and the body so that there is no weight on the leafs
-loosen the u-bolts
-take a hammer and hit the overload spring back into place, so it lines up again
-make sure when you tighten the u-bolts back, they are torqued EVENLY @90ft/lbs

has nothing to do with how tight the u-bolts are (mostly). they should have another spring clamp on them like the one in the top pic foreground.

My vote is for the spring pack centering pin not tight enough.

your right, I did say mostly... the loose u bolts can cause it to happen. but the center bolt is more likely. thanks scuba.

Center bolts keeps the leafs and axle lined up front to back.
Clamps keep the leafs lined up side to side.
Ubolts keep the axle connected to the spring.

The lowest leaf on my front pack used to do that when I took it off road. Clamp the spring.
