Uhm.... when you take what appears to be a flat leaf spring out of a car, does it spring back to normal looking?

72 Imperial, 6,000-lbs - driver side spring was flat across and passenger side had some arch to it - giving me about a 2-inch height difference.

After getting them out - they both appear the same and as arched as the new ones.

Is it only evident that a spring is worn out when it has a full load on it?

Thanks!
