For any mechanism to store the mechanical energy and to function the springs are widely used. In automotive mechanisms widely the springs are used.

Many automotive mechanism premature failure or non conformance is due to the permature of the spring. Hence the spring design, material selection, surface coating of the spring, packaging of the spring in the mechanism, induced bending stress limit etc., are critical.

During design if care is not given then it leads to test failure or field failure.

Many details provided here are based on lessons learnt so the Engineers can benefit out this details
