145 jobs will be cut by Metaldyne auto parts factory in New Castle this July. The decision comes after two contracts with Daimler Chrysler AG end this summer. The factory produces ball joints, steering knuckles and other suspension and chassis parts. Metaldyne also makes parts for Ford and Toyota motor companies. Plant spokeswoman Marge Sorge says other companies are experiencing similar situations as the big three automakers are going through a time of transition.
