A composite leaf spring is being installed. What is the correct procedure?

The correct procedure for installing a composite leaf spring emphasizes the importance of not scratching the spring during installation. Composite leaf springs are made from layered materials, commonly fiberglass or other composites, which are sensitive to physical damage. Scratching the surface can compromise the integrity of the spring, potentially leading to failure during operation.

Proper handling is crucial to maintain the structural integrity and functionality of the spring. Any scratches can create stress concentrations that might lead to premature failure. During installation, care should be taken to avoid contact with sharp objects and to use appropriate tools that won't damage the spring.

The other approaches suggested, such as using a pry bar or vise grips to compress the spring, are not considered safe or standard practice. These methods can lead to damaging the spring or creating an unsafe installation. Additionally, painting the spring after installation is unnecessary as it could also risk damaging the spring's material properties or lead to issues with adhering paint, which may also contribute to premature wear.
