pulley

  1. 01-04.5 LB7 Duramax Powertrain
    The title says it all, it's broken off 3 times and no one can tell me what's causing it. This last time it actually broke the center of the pulley out, right around the p.s. pump shaft... Has anyone had this issue? Is there a fix? Is there anything I can check out? None of the other pulleys...
