shift in spring leaf
shift in spring leaf
(OP)
I am writing about leaf springs on the front axle of trucks. I see that after a short run (unladen also !!) the second leaf from the top shifts to the side by approx 10 mm. this causes it to hit the shackle. I find the U bolt torque to be OK.
I need help to understand if this is normal. what holds the leaves in line.

RE: shift in spring leaf
Could the deviation on the camber on the leaves cause this ?. My thinking is that if the camber of a particular leaf is less than the spec, the preload between the leaves could be lower causing the leaf to slip in service.
Thanks.
