Look like it's been torqued
in the rotation of travel. It's possible this is caused from the TT brakes being applied with great force.
My TT doesn't have leaf springs, but has rubber torsion suspension. The photo below shows something similar happening to my TT.
Notice how the axle moved in the rotation of travel.
I believe this happened as a result of a sudden, hard braking situation. This is the only explanation I can come up with at this time.
